Patent attributes
A power converter includes: capacitors; switches coupled to the corresponding capacitors, wherein the switches switch electrical connection relationships of corresponding capacitors according to operation signals; one or more charging inductors connected in series to one or more corresponding capacitors; one or more discharging inductors connected in series to one or more corresponding capacitors. In a charging process, by switching the switches, a series connection of the capacitors and the corresponding charging inductor(s) is formed between the input voltage and the output voltage, so as to form a charging path. In a discharging process, by switching the switches, each capacitor and one of the corresponding discharging inductors are connected in series between the output voltage and ground voltage level, so as to form plural discharging paths. The charging process and the discharging process are arranged in alternating and repetitive manner, to convert the input voltage to the output voltage.
