Title: A method of controlling an inverter
Inventor: MOHAMED SATHIK
IPC: H02P29/024
Filed: 2015-12-10
Abstract: An inverter comprises a single-phase inverter arrangement having a complementary pair of power switches controlled with a modulating signal to output an AC signal. The inverter is controlled such that if either one of the pair of power switches is judged to be in a short circuit condition, a shutdown operation is executed to switch off the corresponding one of the pair of power switches. The arrangement detects a short circuit fault in a power switch, and controls the gate voltage VGE to limit the fault current and so minimising voltage or thermal stress on the power switch. The control of the gate voltage ensures that the power switch is turned off with the Short Circuit Withstand Time (SCWT) of the power switch. The step of judging whether either one of the pair of power switches is in a short circuit condition may comprise the steps of: monitoring a collector‐emitter voltage VCE of each of the pair of power switches; and if the collector‐emitter voltage exceeds a predetermined value, the corresponding one of the pair of power switches is judged to be in a short circuit condition.
