| Abstract: | A digital PI voltage integral regulating method, as proposed in the paper is directed at overcoming the flux imbalance phenomena in the SPWM full-bridge inverter. The method involves adopting a digital PI controller to sample the primary winding voltage and adjusting the width of trigger pulses. The approach proves practical and effective. |
