Abstract:
1. A circuit, having at least one partial circuit for feeding at least one inverter circuit that is connectable to a power grid, wherein each partial circuit comprises: an unregulated voltage source having a temporally variable output DC voltage; a synchronous converter having a first capacitor, connected between the first terminals of a switching stage of said synchronous converter and a series circuit of second capacitors at their second terminals; and in at least one lead line between said first capacitor and said first terminals, at least one coil having a DC voltage source for supplying a regulating circuit for triggering said synchronous converter with a plurality of measuring devices; wherein said switching stage of said synchronous converter comprises at least one converter stage which includes a series circuit of first, second, third and fourth power transistors, each with one anti-parallel-connected diode, in which said first power transistor is connected to a second terminal of positive polarity; a center point between said first power transistor and said second power transistor is connected to a first terminal of positive polarity; a center point between a third power transistor and said fourth power transistor is connected to a first terminal of negative polarity; and said fourth power transistor is connected to a second terminal of negative polarity.
