When the secondary voltage increases in the flyback circuit, the voltage of the bias winding also increases in proportion. When this voltage increase is detected by zener diode ZD1, a latched shutdown is accomplished. As the secondary voltage is detected through a transformer, detection accuracy is low. 3-2 The method of detecting an overvoltage (detection on secondary side) A typical latched shutdown circuit to protect against overvoltages detected on the secondary side is shown in Fig. 12. The detected voltage accuracy is high compared to overvoltage detection on the primary side. 3-3 The method of detecting an overcurrent (detection of primary current) A typical primary overcurrent detection circuit is shown in Fig. 13. 3-4 The method of detecting an overcurrent (detection of secondary current) A typical secondary overcurrent detection circuit is shown in Fig. 14. |
