Abstract: The present invention provides a gate drive for protecting a switching element (IGBT) used for an electrical inertial load controller. A high-voltage IGBT is used as the switching element and an hcp1316j is used as the gate drive of the IGBT, to restrict overvoltage and overcurrent generated in the event of inverter switching, preventing destruction of the IGBT in advance. Furthermore, an RC filter is formed in close proximity to the IGBT to minimize an erroneous switching operation due to harmonics generated caused by noise in case of inverter switching to improve the system reliability and block an increase in abnormal voltage applied across the switching element.
