SYSTEMS AND METHODS FOR PROTECTING POWER CONVERSION SYSTEMS BASED ON AT LEAST FEEDBACK SIGNALS |
摘要 |
System and method for protecting a power conversion system. An example system controller includes a protection component and a driving component. The protection component is configured to receive a demagnetization signal generated based on at least information associated with a feedback signal of the power conversion system, process information associated with the demagnetization signal and a detected voltage generated based on at least information associated with the feedback signal, and generate a protection signal based on at least information associated with the detected voltage and the demagnetization signal. The driving component is configured to receive the protection signal and output a driving signal to a switch configured to affect a primary current flowing through a primary winding of the power conversion system. The detected voltage is related to an output voltage of the power conversion system. The demagnetization signal is related to a demagnetization period of the power conversion system.
