APPARATUS AND METHOD FOR CONTROL OF SEMICONDUCTOR SWITCHING DEVICES
摘要
Disclosed is a control circuit for control of a semiconductor switching device, such as an IGBT. The control circuit comprising a first feedback path between a first electrode and a control electrode of said semiconductor switching device which has a capacitance. The circuit is operable such that the capacitance in the first feedback path is dependent on the voltage level at said first electrode. In another embodiment the control circuit is operable such that a feedback signal begins to flow in the first feedback path immediately as the semiconductor switching device begins switching off, thereby causing a control action on the semiconductor switching device.
