Claim 6:
7. The power converter of claim 6, wherein said inductor is connected in series with said AC input, said low-voltage capacitor, said two high-voltage power switches connected between said first AC terminal of said AC port and opposed ends of said high-voltage capacitor, said two intermediate low-voltage power switches connected between said opposed end of said high-voltage capacitor and opposed ends of said low-voltage capacitor, and said two terminal low-voltage power switches connected between said opposed ends of said low-voltage capacitor and said second AC terminal of said AC port;
wherein each of said plurality of DC ports be connected to said opposed ends of said high-voltage capacitor; and
wherein said controller works in an inverter mode to generate and apply to said two high-voltage power switches, said two intermediate low-voltage power switches and said two terminal low-voltage power switches signal waveforms comprising a first control signal for causing said low-voltage capacitor to be series connected with said DC port and said AC port and charged to a predetermined value proportional to a Voltage of said DC port, and a second control signal for causing said low-voltage capacitor to be disconnected from the DC port and series connected with the AC port, thereby causing the low-voltage capacitor to be discharged.
