Abstract
A system can include a bi-directional converter circuit comprising a plurality of switches and at least one flying capacitor. One or more the plurality of switches can experience overvoltage in a fault state. The system can include a control module operatively connected to the plurality of switches to control a state of the plurality of switches. The control module can be configured to receive a sense signal indicative of flying capacitor voltage and to control the one or more switches of the plurality of switches to turn on or remain on to prevent switch overvoltage of the one or more switches if the flying capacitor voltage is outside of a normal range.
