Abstract
This paper analyzes the PWM control method for a new type of step-up DC/DC converters with galvanic isolation - the quasi-Z-source inverter (qZSI) based DC/DC converter. The PWM control method for qZSI with soft-switching capability is proposed and experimentally proved. The operation principles of discussed converter are explained. The experimental verification and analysis of top and bottom IGBTs of inverter bridge has been made. A prototype has been built in the laboratory and experiments are presented to analyse the soft-switching capability in loss reduction.
