CIRCUIT ARRANGEMENT AND METHOD FOR GENERATING AN AC VOLTAGE FROM A PLURALITY OF VOLTAGE SOURCES HAVING A TEMPORALLY VARIABLE DC OUTPUT VOLTAGE

摘要

The arrangement has partial circuits (10) connected in parallel and provided for supplying power to an inverter circuit (50) that is connected with a transformer (80). The partial circuits comprise an unregulated voltage source having a temporally varying direct-current output voltage, a voltage doubling circuit (20) and a voltage regulating circuit (40) with a regulating device. A half-bridge circuit has two power transistors, and two capacitors are connected in series, where the voltage regulating circuit is designed identical to the voltage doubling circuit. An independent claim is also included for a method for controlling a circuit arrangement.
