System of current amplifier power supply, consisting of two blocks containing available impulse amplifiers, each of them including transistor key input connected with non-stabilised constant voltage source and its output with cathode of the diode and a choking coil, which in turn is connected with input of the power supply amplifier and positive cover of the condenser, whereas anode of the diode is connected with non-stabilised constant voltage source and, through the first resistor, with negative cover of the condenser, while the first resistor is connected to the input of the transistor key of the maximum current comparator, while the output of the said comparator is connected , through the control circuit, with control input of the transistor key; is characterised in that between the negative condenser cover (C) and the housing of the system is connected second resistor (Ro), which is also connected to input of the second comparator (Ik- Io), comparing current (Ik), at the transistor key (T) with current (Io) powering the power amplifier (WM), while power input (WZ) of the power amplifier (WM) and output (WYJ) of the power amplifier (WM) are connected with inputs of the third comparator (Uzas-Uwyj), while outputs of the second and third comparators (Ik- Io) and (Uzas-Uwyj) are connected, through the control circuit (US) with the transistor key (T).<IMAGE>
