Abstract

A capacitor module, a method of manufacturing the same, and a vehicle inverter having the same. A capacitor module may include: a case configured to have an opening formed on one surface thereof; and a plurality of multilayer ceramic chip capacitor arrays disposed inside the opening and configured to include a set Multiple Multilayer Ceramic Chip Capacitors (MLCCs) in it.

Description

[0001] Cross References to Related Art [0002] This application claims the benefit of Korean Patent Application No. 10-2013-0168240 filed on December 31, 2013, the entire contents of which are incorporated herein by reference. technical field [0003] Exemplary embodiments of the present invention relate to a capacitor module, and more particularly, to a capacitor module using a multilayer ceramic chip capacitor (MLCC), and a method of manufacturing the same. [0004] In addition, exemplary embodiments of the present invention relate to an inverter for a vehicle using a capacitor module of a multilayer ceramic chip capacitor. Background technique [0005] In an automotive inverter, a direct current (DC) capacitor is electrically connected in parallel between a battery and an insulated gate bipolar transistor (IGBT) to rectify power and absorb switching noise, thereby stabilizing the power system. Such a DC capacitor is generally configured with a film type capacitor having...
