Abstract
An object of the present invention is to provide a semiconductor oscillation suppression circuit capable of suppressing voltage oscillation of a switching element with low loss. A semiconductor oscillation suppression circuit includes a wide-bandgap semiconductor element and a capacitor connected to the wide-bandgap semiconductor element in parallel and having a larger capacity than a junction capacitance of the wide-bandgap semiconductor element.
