摘要： A control circuit with protection circuit for power supply according to the present invention comprises a peak-detection circuit and a protection circuit. The peak-detection circuit detects an AC input voltage and generates a peak-detection signal. The protection circuit comprises an over-voltage protection circuit. The over-voltage protection circuit generates an over-voltage protection signal in response to the peak-detection signal. The protection circuit generates a reset signal to reduce the output of the power supply in response to the over-voltage protection signal. The present invention can protect the power supply in response to the AC input voltage effectively through the peak-detection circuit.
摘要翻译：根据本发明的具有电源保护电路的控制电路包括峰值检测电路和保护电路。峰值检测电路检测交流输入电压并产生峰值检测信号。保护电路包括过电压保护电路。过电压保护电路响应峰值检测信号产生过电压保护信号。保护电路产生复位信号，以响应过电压保护信号减小电源的输出。本发明可以通过峰值检测电路有效地响应于AC输入电压来保护电源。
