Title: Overcurrent protecting circuit
Inventor: HONDA AKIRA
IPC: H02M3/28
Filed: 1985-06-24
Abstract: PURPOSE:To alleviate power loss at overload time by shortening the ON time of a main switching transistor when a current larger than a reference flows. CONSTITUTION:If an overcurrent flows to the secondary side of a transformer T, a current which flows to a main switching transistor Q2 through the transformer T increases. Then, if a voltage VBEQ1 between the base and the emitter of a sub switching transistor Q1 rises to exceed the threshold voltage of the transistor Q1, the transistor Q1 is turned ON. Then, when the transistor Q1 is turned ON, it operates to reduce the equivalent differentiating resistor value of a controller C.U. If the resistor value decreases, the output pulse from the controller C.U. to the transistor Q2 is narrowed in the pulse width. Thus, the ON time of the transistor Q2 is shortened to alleviate power loss at overload time.

The value of the load resistance of the detector 32 can be set at an optimum level for servo purpose since both detectors 32 and 36 are independent of each other. At the same time, the value of the load resistance of the detector 36 can be set at an optimum level for reproduction purpose. Therefore no limitation is given to the frequency band of a reproduced signal. Thus it is possible to obtain a reproduced signal having a wide range of frequency bands with an excellent S/N.
