Abstract
PURPOSE: To restrict the rush current of a switching type constant-voltage circuit at switch closing time by adding a diode to a smoothing circuit.
CONSTITUTION: The secondary winding of a choke transformer 7 inserted into a primary circuit is connected at one end thereof the cathode of a diode 6 and at the other to one end of a smoothing condenser 3. A diode 16 is so connected to the connecting point of the transformer 7 to the condenser 3 that rectified output current may not flow directly to the smoothing condenser 3 of the rectifying circuit 2. When a transistor 11 is conducted, a current is flow from the choke transformer 7 to the condenser 3, while when the transistor 11 is shut off, it is flown through the diode 6 to the condenser 3, but due to a diode 16 the rectified output current will not directly flow to the condenser 3. The diode 16 is conducted only when the potential across the condenser 3 is higher than the rectified output voltage to allow the energy stored in the condenser 3 to be discharged through the diode 16.
