Abstract

The invention involves a DCDC power supply, including supporting electronic circuits which generate a voltage level suitable for electrocoagulation, in particular blood electrocoagulation. The power supply consists of a power accumulator (1) bridged by the capacitor input block (2), where the input capacitor block (2) supplies the control circuit (3), the control circuit (3) controls the electronic switching element (4) to the control circuit (3), a feedback compensation element (12) is connected bidirectionally, a ferrite transformer (5) is connected to the electronic switching element (4). The ferrite transformer (5) is connected both to the input capacitance block (2) and to the current measuring circuit (13) by the transformer (5) and to the output voltage rectifier (6). The circuit (13) is connected to the control circuit (3). The feedback resistive voltage divider (11) is connected to both the control circuit (3) and the output voltage rectifier (6) and the output voltage rectifier (6) is also connected to the capacitor output block (7), where the output capacitor block (7) is also connected to a circuit (8) for converting a continuous DC voltage to a to non-continuous DC voltage. The circuit (8) is connected to the output filter member (9) and the output filter member (9) is connected to the output terminals (10) of the source. The supply source generates an AC voltage of up to 150 V and 500 kHz frequency.
