Abstract
An inverter includes a positive electrode terminal and a negative electrode terminal, upper-arm switching elements and lower-arm switching elements, and a voltage divider that supplies partial voltages of a voltage between the positive electrode terminal and the negative electrode terminal to a gate and a drain, respectively, of the lower-arm switching element. The lower-arm switching element includes an HEMT. In the voltage divider, the partial voltages are set to turn the lower-arm switching element off when a positive electrode and a negative electrode of a DC power supply are reversely connected to the positive electrode terminal and the negative electrode terminal, respectively.
