STM32F103单片机逆变器源码,大家知道， 市电或其他的交流电可以通过二极管或可控硅的单向导电性整流成直流电供 给需要使用直流电的场合。这种把交流电变换成直流电的过程我们叫做整流，也叫做顺变。 那么逆变呢？我们自然地就会想到，应该就是把直流电变换成交流电的过程。逆变电源就是 相对于整流器而言通过半导体功率开关器件的开通和关断把直流电变换成交流电的这么一 个装置。 逆变电源也叫做逆变器.(STM32F103 microcontroller inverter source, we all know, city power or other AC can be diode or SCR one-way conductivity rectifier into DC power supply For occasions requiring direct current. This process of converting alternating current into direct current is called rectification, which is also called commutation. What about inverting? We naturally think of the process of converting direct current into alternating current. Inverter power is As opposed to a rectifier, the direct current is converted into alternating current through the turn-on and turn off of the semiconductor power switching device Unit. An inverter is also called an inverter)
