Abstract
A circuit device includes a diode bridge having a first power input and a second power input and having a first output terminal and a second output terminal. The diode bridge includes a plurality of diodes and a respective plurality of diode bypass elements associated with the plurality of diodes. The circuit device further includes a logic circuit to detect a power event at the first and second power inputs and to selectively activate one or more of the respective plurality of diode bypass elements in response to detecting the power event to limit a rectified power supply at the first and second output terminals.
