Abstract
Systems and processes for protecting a power converter against overvoltage conditions are disclosed. In one example, an overvoltage protection circuit may be used to sense the input voltage of the power converter to determine whether the input voltage is greater than a threshold value. In response to determining that the sensed input voltage is greater than the threshold value, an input capacitance and/or capacitance of an EMI filter of the power converter may be discharged to ground or an input return through a tapFET of a switching element of the power converter to protect the components of the device. The capacitance(s) may continue to be discharged through the tapFET for a duration of time after the sensed input voltage falls below the threshold value to allow the capacitance(s) to discharge to a safe level.
