Voltage-boosting converters with hybrid energy pumping

摘要

Voltage-boosting converters with hybrid energy pumping are presented. Hence, the corresponding voltage conversion ratios are higher than the traditional boost converter or some existing voltage-boosting converters. Above all, by changing the circuit connection or turn-on types of switches, there are three voltage conversion ratios to be generated. Hence, there are three types of voltage-boosting converters to be presented herein. Furthermore, for any type, no isolated gate driver is needed instead of one half-bridge gate driver and one low-side gate driver, and the voltage stress on the low-side switch to magnetise the inductor and the voltage stress on the output diode can be reduced as compared to the traditional boost converter. In addition, the basic operating principles of these converters are easy to describe and analyse along with mathematical deductions.
