Abstract
An inverter control apparatus is provided that offers a 'soft turn off' to a gate operation of the inverter so as to securely protect the IGBT. In particular, an inverter control system according to the present invention may include a gate operating portion that controls turn on/off of an IGBT and forcibly turns off the IGBT if a short circuit or an over current is detected from the IGBT, a current buffer that amplifies a control current for the turn on/off of the IGBT that is outputted from the gate operating portion, and a filter that delays the forcible turn off control current that is outputted from the gate operating portion.
