Abstract

A resonant switching power converter includes: capacitors; switches; at least one charging inductor; at least one discharging inductor; a controller generating a charging operation signal corresponding to charging process and discharging operation signals corresponding to discharging processes, to operate the switches to switch electrical connection relationships of the capacitors. In the charging process, the controller controls the switches via the charging operation signal, so that a series connection of the capacitors and the charging inductor is formed between the input voltage and the output voltage, which forms a charging path. In the discharging processes, the controller controls the switches via the discharging operation signals, so that a series connection of one of the capacitors and the discharging inductor is formed between the output voltage and a ground voltage level, to form plural discharging paths at different periods in a sequential order.
