Abstract
A circuit comprising at least one parallel-connected partial circuit for feeding at least one inverter circuit. A partial circuit consists of an unregulated voltage source having a temporally varying DC output voltage, a voltage doubling circuit and a voltage regulating circuit with an associated regulating device. In the inventive method, the voltage doubling circuit doubles the voltage of the unregulated voltage source. The regulation of the current/voltage characteristic curve, the MPP tracking, of the unregulated voltage source is effected by the regulating device of the voltage regulating circuit.
