摘要
The circuit for detecting the breakdown of a switching transistor and for detecting the regnerated voltage by main controller includes a pulse generator (1) for generating high signal at normal operation mode and low signal when the detected voltage exceeds the reference voltage, and a detector (2) for examining the fault of a transistor (Q4) utilizing the node voltages (A,B,C).
