Patent JP-S62157421-A (JP)
Title: Overcurrent protection circuit
Inventor: KURODA EIJU
IPC: H02M3/28
Filed: 1985-12-28
Abstract: PURPOSE:To protect the circuit by decreasing an oscillation frequency at overload so as to decrease the duty ratio of a conduction period control pulse thereby decreasing the average current flowing to a main switching transistor (TR). CONSTITUTION:If a load short-circuit takes place and a voltage of a main switching current signal at a terminal 28 exceeds a reference voltage VR, an output of a comparator 11 brings an output terminal Q of a flip-flop FF 14 to a high level, its output brings an output level of an inverter 13 to a signal level non-conducting the main switching TR and starts the charging of a capacitor 19. When a Q output of the FF 14 goes to a low level when one cycle of the oscillation output of an oscillation section 26 is finished. When a main switching current signal reaches a higher state than a voltage VR, the said state is repeated, the terminal voltage of the capacitor 19 rises gradually to conduct a TR 8 even in the next cycle. Thus, the oscillation frequency of the oscillation section 26 is lower than the conventional state. Thus, the duty ratio of the output pulse of the inverter 13 is decreased and the average current of the main switching TR is lowered.
