Abstract

The cascaded H-bridges with carrier phase-shift SPWM can increase the equivalent switching frequency and improve the output voltage quality. When the cascaded H-bridges topology is applied to the line-frequency inverter power supply, the bulky magnetic components limit the power density of the power supply. This paper integrates the isolation transformers and filter inductors in the power supply, and develops an optimization design method of the transformer. Through integration and optimization design, the volume power density of the transformer is increased by 69.6%, and the weight power density is increased by 44.8%.
