Control circuit with protection circuit for power supply |
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. |

1. A control circuit with protection circuit for power supply, comprising:
a peak-detection circuit, detecting an AC input voltage of the power supply to generate a peak-detection signal; and a protection circuit, comprising an over-voltage protection circuit generating an over-voltage protection signal in response to the peak-detection signal for an over-voltage protection when an amplitude of the AC input voltage is too high, wherein the protection circuit generates a reset signal to reduce an output of the power supply in response to the over-voltage protection signal. |
