Abstract
First and second semiconductor elements are connected in series between a DC positive bus and a DC neutral point bus. Third and fourth semiconductor elements are connected in series between the DC neutral point bus and a DC negative bus. Fifth and sixth semiconductor elements are connected in series between a connection point of the first and second semiconductor elements and a connection point of the third and fourth semiconductor elements. Each semiconductor element includes at least one semiconductor switching element and at least one diode. A breakdown resistance of the first and fourth semiconductor elements to cosmic rays is higher than a breakdown resistance of the second and third semiconductor elements to cosmic rays. A breakdown resistance of the fifth and sixth semiconductor elements is higher than the breakdown resistance of the first and fourth semiconductor elements.
