Abstract
The present invention relates to an insulated gate bipolar transistor (IGBT) driver module for driving at least one gate of at least one IGBT device, and method therefor. The IGBT driver module comprises at least one series capacitance operably coupled between a driver component of the IGBT driver module and the at least one gate of the at least one IGBT device. The IGBT driver module further comprises at least one series capacitance charge adjustment component controllable to determine a gate voltage error (ΔGerr) at the at least one gate of the at least one IGBT device and dynamically adjust a charge of the at least one series capacitance based at least partly on the determined gate voltage error (ΔGerr).
