给出了一种最新的实现AC-DC-AC转换的电源研制过程,由单相交流220V电压输入,经过不可调控整流电路和可控斩波电路,再进入可控逆变电路,最终得到连续可调的单相正弦波交流输出电压。同时,控制单元根据输入的同步信号,可以调节调制波的相位,实现输出电压相位0～360范围内的调节,并且通过使用跳线电平来选用不同频率的电压。实验结果证明了此电源装置研制的可行性、有效性和实用性。
Development process of the newest way to achieve AC-DC-AC conversion power supply was given, via single-phase 220 V AC input through uncontrollable rectification circuit and controllable chopper circuit, then to controllable inversion circuit and finally to get to continuously adjustable single-phase since wave output voltage. Meanwhile, according to input sync signal, the control unit can adjust the phase of modulation waveform to realize voltage phase adjustment in the range of 0-360° and voltage with different frequency can be chosen by the level of jumper wire. Experimental results have proven the feasibility, effectiveness and practicability of this power device development.
