Abstract
An object is to provide a technique that eliminates the need for an external circuit for enhancing the breakdown voltage. A switching element drive circuit includes a primary circuit and a secondary circuit, and an insulating element isolating the primary circuit and the secondary circuit from each other in terms of a direct current. The secondary circuit includes a semiconductor substrate, a detector provided on a portion of the semiconductor substrate, including a pn junction isolation portion, and configured to detect a voltage of a high voltage terminal, and a controller provided on a remaining portion of the semiconductor substrate and configured to control a control voltage of a semiconductor switching element based on a second signal and a detection result of the detector.
