Power converter circuit and method for feeding into the mains from a DC source with a non constant DC

摘要

The arrangement has an input inductor (20) and an H-bridge (60) with flow-control valves (620, 660, 720, 760) per branch, where each flow-control valve has a switchable forward-biasing and a reverse-biasing. The flow control valves are connected with a capacitor (82) between both branches of alternating current connectors of the H-bridge. The flow control valves have a series arrangement of diodes and transistors . An independent claim is also included for a method for converting non constant direct current into alternating current.
