L6561 应用笔记中文版L6561 ，增强版的临界模式功率因数校正器TM（临界模式）技术广泛应用于低功率产品的功率因数校正，例如灯具镇流器，视频终端控制电路。

L6561是后期针对这个市场推出的产品，不但符合要求而且是一款低价的功率因数校正器。

基于一个非常好的电路架构，L6561展现出非常优越的性能，而且应用领域更为广泛。

介绍传统的单级离线式转换电路，都是由一个全桥整流和一个电容滤波构成。

通过交流主线电源获得一个未校准的直流电压，滤波电容必须足够大以便可以得到一个纹波电压比较小的直流电压，这就意味着在大多数时间内，电容上的电压高于输入AC电源线电压，这就意味着，全桥整流电路仅在输入线电压每半周期内（因为有整流桥的存在，整流后的每个周期相当于AC电源的半个周期），工作很短的时间。

使得从电网输入的电流变成很窄的脉冲波形，其幅度是同等直流电压下电流幅度的5-10倍。

许多缺点因此而产生：过高的峰值电流和RMS电流比，使得交流电网电压畸变，在三相线输电电网中，使中性线过电流，总之，会使电网的输电能力减弱。

关于这项指标，可以参考谐波允许量标准EN61000-3-2,或功率因数PF，有功功率（传送到输出端的功率）和输入视在功率（线电压真有效值和线电流真有效值的乘积）的比值，功率因数PF是最直观的。

传统的输入电容滤波电路功率因数很低（05-0.7），并且谐波含量很高。

图1. L6561内部模块图由于使用了开关技术，功率因数矫正器（PFC）位于整流桥和滤波电容之间，从电源获取一个准正弦波电流，与线电压同步，功率因数变得非常接近1（可以超过0.99），上述的缺点得以消除。

从理论上来讲，任何开关拓扑技术都可以用来获取一个高功率因数，但是，实际应用中，升压拓扑是一种最流行的方式，因为它有以下优势：1）主要是，因为升压电路所需的元件最少，因此这种方式最便宜。

还有：2）由于升压电感位于整流桥和开关之间，引起的电流di/dt比较低，可以使输入产生的噪音最小化，可以减少输入EMI滤波元件。

the addition of a high voltage start-upsource. These functions make the IC especially suitable for applications that have to becompliant with energy saving regulations and where the PFC pre-regulator works as themaster stage.The highly linear multiplier, along with a special correction circuit that reduces crossoverdistortion of the mains current, allows wide-range-mains operation with an extremely lowTHD even over a large load range.The output voltage is controlled by means of a voltage-mode error amplifier and an accurate(1% @Tj = 25 °C) internal voltage reference. Loop's stability is optimized by the voltagefeedforward function (1/V2 correction), which in this IC uses a proprietary technique thatconsiderably improves line transient response as well in case of mains both drops andsurges (“bidirectional”).Additionally, the IC provides the option for tracking boost operation, i.e. the output voltage ischanged tracking the mains voltage.The device includes disable functions suitable for remote ON/OFF control too.In addition to an over voltage protection able to keep the output voltage under control duringtransient conditions, the IC is provided also with a protection against feedback loop failuresor erroneous settings. Other on-board protection functions allow that brownout conditionsand boost inductor saturation can be safely handled.An interface with the PWM controller of the DC-DC converter supplied by the PFC pre-regulator is provided: the purpose is to stop the operation of the converter in case ofanomalous conditions for the PFC stage (feedback loop failure, boost inductor's coresaturation, etc.) and to handle the PFC stage in case of light load for the DC-DC converter,to make it easier to comply with energy saving regulations (Blue Angel, EnergyStar,Energy2000, etc.).The totem-pole output stage, capable of 600 mA source and 800 mA sink current, is suitablefor big MOSFET or IGBT drive. This, combined with the other features and the possibility tooperate with ST's proprietary fixed-off-time control, makes the device an excellent solutionfor SMPS up to 400 W that need to be compliant with EN61000-3-2 and JEIT A-MITIstandards.6/49Doc ID 16047 Rev 3L6563H Maximum ratingsDoc ID 16047 Rev 37/492 Maximum ratings2.1Absolute maximum ratings2.2 Thermal dataTable 1.Absolute maximum ratingsSymbol Pin ParameterValue Unit V HVS 9Voltage range (referred to ground)-0.3 to 700VI HVS 9Output currentSelf-limited I HVS Vcc 16IC supply voltage (Icc = 20 mA)self-limited V ---1, 3, 7Max. pin voltage (I pin =1 mA)Self-limited V ---2, 4 to 6, 8, 11, 12Analog inputs and outputs-0.3 to 8V I PWM_STOP11Max. sink current3mAI ZCD13Zero current detector max. current-10 (source)10 (sink)mATable 2.Thermal dataSymbol ParameterValue Unit R thJA Max. thermal resistance, junction-to-ambient 120°C/W Ptot Power dissipation @T A = 50 °C 0.75W T J Junction temperature operating range -40 to 150°C T stgStorage temperature-55 to 150°CPin connection L6563H8/49Doc ID 16047 Rev 33 Pin connectionTable 3.Pin descriptionn°NameFunction1INVInverting input of the error amplifier. The information on the output voltage of the PFC pre-regulator is fed into the pin through a resistor divider.The pin normally features high impedance but, if the tracking boost function is used, an internal current generator programmed by TBO (pin 6) is activated. It sinks current from the pin to change the output voltage so that it tracks the mains voltage.2COMPOutput of the error amplifier. A compensation network is placed between this pin and INV (pin 1) to achieve stability of the voltage control loop and ensure high power factor and low THD. T o avoid uncontrolled rise of the output voltage at zero load, when the voltage on the pin falls below 2.4 V the gate driver output is inhibited (burst-mode operation).3MULTMains input to the multiplier. This pin is connected to the rectified mains voltage via a resistor divider and provides the sinusoidal reference to the current loop. The voltage on this pin is used also to derive the information on the RMS mains voltage.4CSInput to the PWM comparator. The current flowing in the MOSFET is sensed through a resistor, the resulting voltage is applied to this pin and compared with an internal reference to determine MOSFET’s turn-off.A second comparison level at 1.7 V detects abnormal currents (e.g. due to boost inductor saturation) and, on this occurrence, activates a safety procedure that temporarily stops the converter and limits the stress of the power components.5VFFSecond input to the multiplier for 1/V 2 function. A capacitor and a parallel resistor must beconnected from the pin to GND. They complete the internal peak-holding circuit that derives the information on the RMS mains voltage. The voltage at this pin, a dc level equal to the peak voltage on pin MULT (3), compensates the control loop gain dependence on the mains voltage. Never connect the pin directly to GND but with a resistor ranging from 100 k Ω (minimum) to 2 M Ω (maximum).6TBOT racking boost function. This pin provides a buffered VFF voltage. A resistor connectedbetween this pin and GND defines a current that is sunk from pin INV (1). In this way, the output voltage is changed proportionally to the mains voltage (tracking boost). If this function is not used leave this pin open.L6563H Pin connectionDoc ID 16047 Rev 39/497PFC_OKPFC pre-regulator output voltage monitoring/disable function. This pin senses the outputvoltage of the PFC pre-regulator through a resistor divider and is used for protection purposes. If the voltage on the pin exceeds 2.5 V the IC stops switching and restarts as the voltage on the pin falls below 2.4 V . However, if at the same time the voltage of the INV pin falls below 1.66V , a feedback failure is assumed. In this case the device is latched off and the PWM_LA TCH (8) pin is asserted high. Normal operation can be resumed only by cycling Vcc bringing its value lower than 6V before to move up to Turn on threshold.If the voltage on this pin is brought below 0.23 V the IC is shut down. T o restart the IC the voltage on the pin must go above 0.27 V . This can be used as a remote on/off control input.8PWM_LA TCHOutput pin for fault signaling. During normal operation this pin features high impedance. If a feedback failure is detected (PFC_OK > 2.5 V & INV < 1.66V) the pin is asserted high.Normally, this pin is used to stop the operation of the dc-dc converter supplied by the PFC pre-regulator by invoking a latched disable of its PWM controller. If not used, the pin is left floating.9HVSHigh-voltage start-up. The pin, able to withstand 700 V , is to be tied directly to the rectified mains voltage. A 1 mA internal current source charges the capacitor connected between pin Vcc (16) and pin GND (14) until the voltage on the pin Vcc reaches the start-up threshold, then it is shut down. Normally, the generator is re-enabled when the Vcc voltage falls below 6 V to ensure a low power throughput during short circuit. Otherwise, when a latched protection is tripped the generator is re-enabled as Vcc reaches the UVLO threshold to keep the latch supplied.10N.C.Not internally connected. Provision for clearance on the PCB to meet safety requirements.11PWM_STOPOutput pin for fault signaling. During normal operation this pin features high impedance. If the IC is disabled by a voltage below 0.8 V on pin RUN (12) the voltage on the pin is pulled to ground. Normally, this pin is used to temporarily stop the operation of the dc-dc convertersupplied by the PFC pre-regulator by disabling its PWM controller. A typical usage of thisfunction is brownout protection in systems where the PFC pre-regulator is the master stage. If not used, the pin is left floating.12RUNRemote ON/OFF control. A voltage below 0.8 V shuts down (not latched) the IC and brings its consumption to a considerably lower level. PWM_STOP is asserted low. The IC restarts as the voltage at the pin goes above 0.88V . Connect this pin to pin VFF (5) either directly or through a resistor divider to use this function as brownout (AC mains undervoltage) protection.13ZCD Boost inductor’s demagnetization sensing input for transition-mode operation. A negative-going edge triggers MOSFET’s turn-on.14GND Ground. Current return for both the signal part of the IC and the gate driver.15GDGate driver output. The totem pole output stage is able to drive power MOSFET’s and IGBT’s with a peak current of 600 mA source and 800 mA sink. The high-level voltage of this pin is clamped at about 12 V to avoid excessive gate voltages.16VccSupply voltage of both the signal part of the IC and the gate driver. Sometimes a small bypass capacitor (0.1 µF typ.) to GND might be useful to get a clean bias voltage for the signal part of the IC.Table 3.Pin description (continued)n°NameFunctionPin connection L6563H10/49Doc ID 16047 Rev 3分销商库存信息:STML6563HTR L6563H EVL6563H-100W。

概述BL6511集成电路是三相电子电度表的核心计量芯片，采用低功耗设计，外部采用（1.8MHz~3.56MHz的晶体振荡器），芯片静态功耗35mW（典型值），因此可以采用三相阻容分压电源，大大降低了生产成本。

基于此芯片设计的三相电子电度表具有外围电路简单、精度高、稳定性好等特点，适用于三相三线和三相四线电力用户的电能计量。

BL6511是基于数字信号处理的电能计量芯片,有测量正向和负向有功功率的功能。

它可以通过选择采用绝对值或代数和相加之一的方式来计量有功功率和。

CF输出以较高频率的脉冲,用于校验和计算机数据处理，F1和F2输出较低频率的脉冲用于驱动脉冲电机，间接驱动机械字轮计度器计算功率,记录用电量。

片内电源检测电路可以进行掉电检测，当电源低于4V时，将关闭CF,F1,F2的输出。

片内电路结构完全保证电压和电流通道的信号在乘法器前的相位匹配。

这就保证了输入信号在45Hz~65Hz范围内的频率变化对增益基本没有影响。

片内防潜动逻辑可以保证无潜动。
