Abstract
Examples include a variable speed drive and method for controlling such variable speed drive driving an electric motor. The variable speed drive includes an inverter and is able to detect when a specific component (IGBT or freewheeling diode) of a specific switch of the inverter crosses a predetermined voltage threshold. An example method allows determining a state of a specific component based on the detection of the crossing.
