性价比很高的1KW纯正弦波逆变器
这是一款保护功能齐全的正弦波逆变电源模块,采用DC-DC-AC 两级功率
变换架构,其中推挽式DC-DC 电路将来自蓄电池的24V 直流电压变换到
DC335V,再由全桥式DC-AC 将DC335V 的电压逆变成AC220V 50Hz 的标准交流电.该模块的DC-DC 部分采用TL494 控制,DC-AC 部分采用HT1215 芯片控制,该模块采用输入输出完全隔离的方案。
满载和空载时的波形:
之所以称其性价比高,大家可以看到,整套板子下来价钱只有四百元左右。
这和采用了HT1215 芯片后,使其所需要的周边电路比较简单,元器件减少有
直接关系。
既降低了成本,又增强了其可靠性。

网友sp2911:
加容性载,性能如何?好像母线电压较低电池亏电波形畸变会很大?
答:不会的,当电压较低时就不工作了,因此不必担心很大畸变的问题。

正弦波逆变器与方波逆变器的比较和区别000按波形分,逆变器分为正弦波逆变器和方波逆变器。
正弦波逆变器输出的是同我们日常使用的电网一样甚至更好的正弦波交流电,它不存在对电网的谐波污染。
方波逆变器输出的是方波交流电,它正向最大值和负向最大值几乎同时产生,对负载和逆变器本身造成非常大的不稳定影响,其波形质量差,负载能力差,仅为额定负载的40-60%,不能带感性负载。
例如:电动机、继电器、日光灯等带感应的电器。
如果所带的负载过大,方波电流中包含的三次谐波将使流入负载中的容性电流增大,严重时会损坏负载的电源滤波电容。
由于方波逆变电源的缺点比较突出,近年来出现了准正弦波(改良正弦波、修正正弦波、模拟正弦波等)逆变器,其输出波形从正向最大值到负向最大值之间有一个时间间隔,使用效果有所改善。
从总体上来说,正弦波逆变器提供高质量的交流电,能够带动任何种类的负载,但技术要求和成本均高。
修正正弦波车载逆变器可应用于手机、笔记本电脑、电视机、摄像机、CD 机、各种充电器、车用冰箱、游戏机、影碟机。
太阳能,风力发电,救护车,抢险救护,电动工具,车载逆变器、电源转换器的相关说明1.问:按输出波形划分,逆变器分为几类?答:主要分两类,一类是修正正弦波逆变器和纯方波逆变器,另一类是正弦波逆变器。
纯方波逆变器输出的则是质量较差的方波交流电,其正向最大值到负向最大值几乎在同时产生(见下图),这样,对负载和逆变器本身造成剧烈的不稳定影响。
同时,其负载能力差,仅为额定负载的40-60%,不能带感性负载(详细解释见下条)。
如所带的负载过大,方波电流中包含的三次谐波成分将使流入负载中的容性电流增大,严重时会损坏负载的电源滤波电容。
针对上述缺点,我们厂生产的修正正弦波逆变器,其输出波形从正向最大值到负向最大值之间有一个时间间隔(见下图),使用效果大有改善,总括来说,正弦波逆变器提供高质量的交流电,能够带动任何种类的负载,但技术要求和成本均高。

全手工DIY制作的48V-2500W纯正弦波逆变器
选专做48V逆变器的原因有几个,电流小,稳定性能非常好,温度低,不伤电瓶可延长电瓶寿命等等。
有网友在想48V电源不好找,但我认为不是的,电动车很多都是48V,在里面取出就可以了,或者可以用4个12V摩托车电瓶串联取得也可以。
有电动车的朋友不妨买个就不用担心停电了。
