Abstract

PURPOSE:To conduct overcurrent protection at low-rate loss, by providing a detector, which consists of a primary winding of small turns of coil, a secondary winding of prescribed turns of coil, a diode, a capacitor and a resistor, on an iron core having a gap between a commutation diode and an input power source. CONSTITUTION:Voltage is induced on the secondary winding 14 by a transformer 15, and this voltage is charged to a capacitor 17 as a voltage Vc, and in this case, this value is proportional to the intensity of current Icp at the time when a current being detected Ic is switched off. In short, the variation of current Icp is treated as a change in the voltage Vc of the capacitor 17. By thus taking out the voltage proportional to the output current at the time of the overcurrent drooping motion, it is possible to obtain an overcurrent protecting circuit of a simple mechanism and a low-rate power loss.
