CONNECTION OF PULSE REGULATED SOURCE'S CONTROL AND DRIVING CIRCUIT'S SUPPLY

The device will find the application mainly in impulse-controlled power supplies with input mains voltage. The supply control circuits are galvanically connected with primary circuits. A rectified mains voltage supplies the starting circuit (SO) that connects the integration condenser (3) to a voltage stabiliser (NS), the inputs of which are powered by control and excitation circuits. After the converter (M) starts, the control and excitation circuits (BO) are supplied through the voltage stabiliser (NS) from auxiliary winding (33) of the transformer (30) of the converter (M). The converter (M) can be blocking, single-acting or double-acting forward with current-dependent control.
