Monitoring the supply voltage helps prevent voltage failures, component damage, and ensures the efficient operation of the power system.

Original Abstract Submitted

A power supply system for a power electronic circuit of an electric vehicle includes a driver board with components configured to activate the power electronic circuit, a monitoring device configured to monitor the supply voltage, and a circuit assembly having a switching element arranged between an accumulator or a phase of the electric motor and the driver board so that the switching element provides a power supply from the accumulator or electric motor for components of the driver board. When the monitoring device detects a failure or reduction in the supply voltage of a component of the driver board, the monitoring device transfers the switching element from an open state to a closed state, for which the supply voltage has failed or collapsed.
