Title:

SWITCHING ELEMENT UNIT

Document Type and Number:

WIPO Patent Application WO/2014/021112

Kind Code:

A1

Abstract:

To achieve a switching element unit which is capable of comprising a smoothing capacitor, while being reduced in size as a whole unit. A smoothing capacitor (50) is a ceramic capacitor having a dielectric portion (53) that is formed of a ceramic material. The outer surface of the smoothing capacitor (50) comprises an element arrangement surface (S1) that is integrally formed with the dielectric portion (53). A positive electrode-side connection electrode (P1) that is electrically connected to a positive electrode terminal (51) of the smoothing capacitor (50) and a negative electrode-side connection electrode (P2) that is electrically connected to a negative electrode terminal (52) of the smoothing capacitor (50) are formed on the element arrangement surface (S1). A switching element (10) and a diode element that constitute a series element unit are arranged on the element arrangement surface (S1), and a positive electrode-side terminal portion (31) of the series element unit and the positive electrode-side connection electrode (P1) are electrically connected with each other, while a negative electrode-side terminal portion (32) of the series element unit and the negative electrode-side connection electrode (P2) are electrically connected with each other.
