Abstract
There is provided an apparatus and methods for a power conversion device. The method includes rectifying a mains voltage to produce a dc voltage and placing the dc voltage on a bus. The bus is coupled to an output converter and has a switch. The method also includes monitoring the bus voltage using voltage sensing circuitry and determining whether the voltage on the bus exceeds a threshold. If the voltage exceeds a threshold, the switch is turned off.
