Abstract

See full text

Disclosure includes a control method for over voltage protection, suitable for a power converter. The power converter has a rectifier for rectifying an alternative-current voltage into a direct-current input voltage. The direct-current input voltage is sensed and determined whether it locates in a valley. A detection voltage is provided, capable of representing the direct-current input voltage. The detection voltage is compared with a predetermined reference voltage. When the detection voltage exceeds the predetermined reference voltage and the direct-current input voltage is in the valley, an OVP signal is provided to stop the power conversion of the power converter.
