Abstract

A first drive circuit is connected with a first power supply node and a first GND node. A second drive circuit is connected with a second power supply node and a second GND node electrically separated from the first power supply node and the first GND node, respectively. A PN junction portion is formed of a P type part electrically connected with the first GND node, and an N type part electrically connected with the second power supply node. A magnetic coupling element has a first conductor coil and a second conductor coil. The first conductor coil is electrically connected with output nodes of the first drive circuit. The second conductor coil is electrically connected with input nodes of the second drive circuit.
