Abstract

A novel polarity inversion dc-dc power conversion circuit that features the high input to output step-up voltage conversion ratio characteristics is presented for high voltage DC power supply applications. The proposed circuit features the reduced voltage stresses of the components compared to those of the conventional ones. The operational principles of the proposed circuit are analyzed and comparative features are presented. The simulation results and experimental results are presented to verify the validity of the proposed circuit.
