The invention relates to an electric transformer circuit (20) for providing electric power, particularly for an electric power generator (10), comprising a rectifying circuit (24, 3), which can be connected to the electric output (16) of an electric generator (14), an intermediate circuit (24, 4), which is connected to the rectifying circuit on the input side and at the output side is connected to an inverter circuit (26, 5) for generating an AC voltage (U<SUB>AN</SUB>), wherein the intermediate circuit (24, 4) comprises a series connection of two switches (4-1, 4-4) and a series connection of two capacitors (4-5, 4-2), wherein the series connections are connected to each other via capture diodes (4-6, 4-3) and wherein the switches (4-1, 4-4) and the capacitors (4-5, 4-2) are connected to each other in a first middle tap (44). The invention further comprises a control device (30, 32, 34) for the independent control of the switches (4-1, 4-4) and for the control of the inverter circuit (26, 5). The inverter circuit (26, 5) comprises at least one half-bridge circuit (49) connected to the intermediate circuit (24, 3) via a second middle tap (50), wherein the AC voltage (U<SUB>AN</SUB>) generated by the inverter circuit (26, 5) is derived from the potentials at the first and second middle taps (44, 50). |
