DRIVING DEVICE AND SEMICONDUCTOR DEVICE
This abstract first appeared for US patent application 20250088184 titled 'DRIVING DEVICE AND SEMICONDUCTOR DEVICE
Original Abstract Submitted
an embodiment includes a controller and a driver. the controller determines and sets either of a first mode or a second mode. the first mode is set when a direction of a current into a semiconductor element is a forward direction. the second mode is set when the direction of the current into the semiconductor element is a backward direction. the semiconductor includes a reverse conducting igbt having dual gate electrodes. the diving unit generates independent gate signals for the dual gate electrodes in accordance with the setting of the controller. and the driver drives the dual gate electrodes as to shorten an off time of the semiconductor element in the first mode, and as to shorten a reverse recovery time in a diode operation of the semiconductor device in the second mode.
