该方法根据实时采样得到的母线电压修正占空比，无需复杂的运算处理，易于实现。
进一步分析了改进调制方法下前级Boost电路的小信号传递函数，提出了欠阻尼条件下基于微分先行PID算法的光伏电池最大功率点电压跟踪方法。
仿真表明，改进后的两级式单相光伏并网逆变器最大功率点跟踪过程振荡小，光伏电池输出电流平稳，二次谐波电流抑制效果显著。

This method corrects the duty ratio according to the bus voltage obtained by real-time sampling. This is easy to realize without complicated processing. The small signal transfer function of the front-stage Boost circuit using an improved modulation method is analyzed, and a voltage tracking method of the maximum power point of photovoltaic cells based on a differential ahead PID control algorithm in an under-damped condition is proposed. The simulation results show that the improved two-stage single-phase photovoltaic grid-connected inverter has little oscillation in the maximum power point tracking process, the output current of photovoltaic cells is stable, and the second harmonic current suppression effect is remarkable.This work is supported by the Key Science and Technology Project of Henan Province (No. 222102240072).Key words: grid-connected inverter; second harmonic; suppression; switching period averaging; modulation0 引言单相逆变器输出瞬时功率含有2倍工频的波动，导致直流母线电压叠加大量2倍工频纹波(简称2次纹波)[1]。

变压器试验技术经过以往的岁月得到了很大的发展。
其发展经历了这样的过程：从早先的仅仅判断变压器是否能通过耐压试验，到后来的对变压器众多参数的详尽测试。
新的成熟性试验技术的应用，为厂内试验的故障诊断提供了极大的方便。
1.试验分类与试验标准1.1变压器的试验分类：按场地划分：现场试验、工厂试验按制造过程划分：半成品试验、成品试验半成品试验包括型式性半成品试验与例行性半成品试验。
例行性半成品试验：每台半成品均要进行的试验项目，如套管CT试验、电压比测量与联接组标号检定、绕组电阻测量等。
型式性半成品试验：新产品研制过程中要进行的试验项目，如铁心叠装完后，缠绕临时绕组，进行铁心损耗测量等。
成品试验包括：例行试验、型式试验、特殊试验。
例行试验：每台产品出厂前都要进行的试验项目。
型式试验：新产品要进行的试验项目；一般周期为5年；或者没到5年，而原设计产品的制造场地、制造人员、产品原材料、生产设备……，发生了重大变化，也应进行型式试验。
特殊试验：标准规定的特殊项目，以及标准中没有规定，用户与制造厂协商达成一致的试验项目。
1.2试验标准变压器试验应按照一定的标准来进行，这些标准包括：国际标准、国家标准、行业标准、工厂标准。
国际标准→国家标准→行业标准→工厂标准，程度上逐渐严格。
国际标准国际标准公认的有：IEC标准，如IEC60076-XXIEEE标准，如IEEEStdC57.12.xx国家标准GB1094系列，如GB1094.xx行业标准常见的由DL、DL/T、JB、JB/T打头，均为行业标准。
工厂标准有些试验项目的具体数值，国际标准、国家标准、行业标准没有规定或无法规定，需要制定工厂标准(或者称企业标准)做补充规定。
如绝缘电阻、介损等的具体数值需要在工厂标准中给予规定。
2.我国的试验技术水平与特高压输电线路概况2.1我国的变压器试验技术水平我国的变压器试验技术处于国际一流水平，主要表现在以下三个方面：(1)我国输变电工程的快速发展，使试验工程师在超高压、特高压产品的试验方面积累了较为丰富的经验；(2)随着特高压交直流输变电设备的制造，促进了国内相关试验设备、测量仪器的突破性发展；(3)国内建造了许多无与伦比的特高压试验大厅。

Assumes the control inputs arepiecewise constant over the sampling period.◾'foh' — Linear interpolation of the inputs (modified first-order hold). Assumesthe control inputs are piecewise linear over the sampling period.◾'tustin' — Bilinear (Tustin) approximation to the derivative.◾'matched' — Zero-pole matching method of [1] (for SISO systems only).Default: 'zoh'opts Discrete-to-continuous time conversion options, created using d2cOptions. Output Argumentssysc Continuous-time model of the same type as the input system sysd.When sysd is an identified (IDLTI) model, sysc:◾Includes both the measured and noise components of sysd. If the noisevariance is λ in sysd, then the continuous-time model sysc has an indicatedlevel of noise spectral density equal to Ts*λ.◾Does not include the estimated parameter covariance of sysd. If you want totranslate the covariance while converting the model, use translatecov.G Matrix mapping the states xd[k] of the state-space model sysd to the states xc(t) of sysc:x c (k Ts)=G24xd[k]u[k]35.Given an initial condition x0 for sysd and an initial input u0 = u[0], thecorresponding initial condition for sysc (assuming u[k] = 0 for k< 0 is givenby:ExamplesExample 1Consider the following discrete-time transfer function:Suppose the model has sample time T s = 0.1 s. You can derive a continuous-time zero-order-hold equivalent model with the following commands:H = tf([1 -1], [1 1 0.3], 0.1);Hc = d2c(H)Hc =121.7 s + 3.026e-12---------------------s^2 + 12.04 s + 776.7Continuous-time transfer function.Discretizing the resulting model Hc with the default zero-order hold method and sampling time T s = 0.1s returns the original discrete model H (z ):c2d(Hc,0.1)ans =z - 1-------------z^2 + z + 0.3Sample time: 0.1 secondsDiscrete-time transfer function.To use the Tustin approximation instead of zero-order hold, typeHc = d2c(H,'tustin');As with zero-order hold, the inverse discretization operationc2d(Hc,0.1,'tustin');gives back the original H (z ).Example 2Convert an identified transfer function and compare its performance against a directly estimated continuous-time model.load iddata1sys1d = tfest(z1,2,'Ts',0.1);x c (0)=G 24x 0u 035.H (z )=z −1z 2+z +0.3sys1c = d2c(sys1d,'zoh');sys2c = tfest(z1,2);compare(z1,sys1c,sys2c)The two systems are virtually identical.Example 3Analyze the effect of parameter uncertainty on frequency response across d2c operation on an identified model.load iddata1sysd = tfest(z1, 2, 'Ts', 0.1);sysc = d2c(sysd, 'zoh');sys1c has no covariance information. Regenerate it using a zero iteration update with the same estimation command and estimation data:opt = tfestOptions;opt.SearchOption.MaxIter = 0;sys1c = tfest(z1, sysc, opt);h = bodeplot(sysd, sysc);showConfidence(h)The uncertainties of sysc and sysd are comparable up to the Nyquist frequency. However, sysc exhibits large uncertainty in the frequency range for which the estimation data does not provide any information.If you do not have access to the estimation data, use translatecov which is a Gauss-approximation formula based translation of covariance across model type conversion operations.LimitationsThe Tustin approximation is not defined for systems with poles at z = –1 and is ill-conditioned for systems with poles near z = –1.expand allThe zero-order hold method cannot handle systems with poles at z = 0. In addition, the 'zoh' conversion increases the model order for systems with negative real poles, [2]. The model order increases because the matrix logarithm maps real negative poles to complex poles. Single complex poles are not physically meaningful because of their complex time response.Instead, to ensure that all complex poles of the continuous model come in conjugate pairs, d2c replaces negative real poles z = –α with a pair of complex conjugate poles near –α. The conversion then yields a continuous model with higher order. For example, to convert the discrete-time transfer functiontype:Ts = 0.1 % sample time 0.1 sH = zpk(-0.2,-0.5,1,Ts) * tf(1,[1 1 0.4],Ts)Hc = d2c(H)These commands produce the following result.Warning: System order was increased to handle real negative poles.Zero/pole/gain:-33.6556 (s-6.273) (s^2 + 28.29s + 1041)--------------------------------------------(s^2 + 9.163s + 637.3) (s^2 + 13.86s + 1035)To convert Hc back to discrete time, type:c2d(Hc,Ts)yieldingZero/pole/gain:(z+0.5) (z+0.2)-------------------------(z+0.5)^2 (z^2 + z + 0.4)Sampling time: 0.1This discrete model coincides with H (z ) after canceling the pole/zero pair at z = –0.5.More AboutTipsAlgorithms References[1] Franklin, G.F., Powell,D.J., and Workman, M.L., Digital Control of Dynamic Systems (3rd Edition), Prentice Hall, 1997..[2] Kollár, I., G.F.
