An electric machine (20) including MOSFET half-bridge circuitry (90) configured to receive an alternating current signal (74) from a stator (24) and generate a supply voltage (46) as a function of the alternating current signal (74). The machine (20) includes control circuitry (88) configured to detect whether the supply voltage (46) exceeds a first threshold voltage, and govern the MOSFET half-bridge circuitry (90) to shunt the alternating current signal (74) to a reference voltage (64) based on a detection of the supply voltage (46) exceeding the first threshold voltage. Also, a method for protecting the machine (20) during a load dump event that shunts the alternating current signal (74) to the reference voltage (64) in response to detecting that the supply voltage (46) exceeds the first threshold voltage. |
