Study on digital control single-ended forward welding inverter

According to the single-ended forward inverter shortage.This paper proposed a new control scheme for single-ended forward inverter,which is control DC voltage quality by using push-pull circuit before it.So it decreases the output wave of DC voltage.Using soft-switch control and output all kinds of frequency of loads voltage.It can decrease the output device by using the pspice simulation soft ware in output frequency 50 kHz,experiment shows by using DSP 2812 that the control approach can carry our purpose expected,and the control welding system runs stably and reliably.
