Patent ID: 7649754

Claim:
A power conversion network having a first terminal, a second terminal, and a third terminal, comprising, a first circuit branch having a first terminal and a second terminal with said first terminal of said first circuit branch connected to said first terminal of said power conversion network, comprising, first switch means, having a first terminal and a second terminal, and a second circuit branch having a first terminal and a second terminal with said first terminal of said first switch means connected to said first terminal of said second circuit branch, connected in series with said first switch means comprising, second switch means having a first terminal and a second terminal with said first terminal of said second switch means connected to said first terminal of said second circuit branch operable substantially in anti-synchronization to said first switch means, and a series network having a first terminal and a second terminal with said first terminal of said series network connected to said first terminal of said second circuit branch connected in parallel to said second switch means comprising, a first capacitor having a first terminal and a second terminal, and a first inductor having a first terminal and a second terminal with said first terminal of said first capacitor connected to said first terminal of said first inductor, third switch means having a first terminal and a second terminal with said first terminal of said third switch means connected to said second terminal of said power conversion network and with said second terminal of said third switch means connected to said second terminal of said first circuit branch, operable substantially in anti-synchronization to said first switch means, a second inductor having a first terminal and a second terminal with said first terminal of said second inductor connected to said third terminal of said power conversion network and said second terminal of said second inductor connected to said second terminal of said first circuit branch, wherein the coupling coefficient for mutual magnetic coupling of said first inductor to said second inductor is substantially zero, whereby said terminals of said power conversion network are connected to an input source of dc voltage and power, an output load, and a return common to both said input source of dc voltage and power and said output load to form a complete power conversion circuit.
