Abstract
An operating condition monitor () for monitoring an operating condition of a transistor-based power converter (), comprising: a sensing apparatus () configured to measure a turn-off transient energy of the power converter (), a processor () in communication with the sensing apparatus () to receive the measurement of the turn-off transient energy, the processor being configured to: compare the measurement of the turn-off transient energy to a threshold; and issue an event signal based on the comparison to the threshold meeting a comparison criterion. A method (') of monitoring an operating state of a transistor-based power converter is also disclosed.
