| Abstract: | A DC/AC converter based on BUCK converter is presented and the converter＇s working principle is taken.The main circuit uses dual-BUCK converter, dual power supply and dsPIC30F4011 MCU as controller .The converter is simulated in the PSIM software .The parameters adopted in the realis-tic simulation ,waveforms such as voltage of modulation reference and load were given ,and a set of labora-torial circuit was built .The parameters of experimentation and the measured waveforms of some interrelat-ed voltage are shown .It is proved that adopting the DC/AC conveter based on BUCK circuit can achieve a line frequency as 50 Hz. |
