Abstract

The invention discloses a self-spliced combined plate-shaped film capacitor which comprises a plurality of plate-shaped capacitor substrates and a plurality of capacitor corner connecting boards. After two sides of each of the plurality of plate-shaped capacitor substrates are spliced with two sides of the capacitor corner connecting board, an annular member is formed. Two sides of the plate-shaped capacitor substrate are provided with substrate butt-joint fixing-and-fastening interfaces which can be plugged with each other, and locking is performed after the substrate butt-joint fixing-and-fastening interfaces are plugged in place. Two sides of the capacitor corner connecting board are provided with interfaces for connecting with the substrate butt-joint fixing-and-fastening interfaces ofthe plate-shaped capacitor substrate and realizing locking. The capacitor is also provided with an electrode interface. The self-spliced combined plate-shaped film capacitor improves power density ofa motor controller and furthermore reduces occupation space in vehicle arrangement.

Description

technical field [0001] The invention relates to capacitor technology, in particular to a self-splicing combined plate type film capacitor. Background technique [0002] Figure 1a and Figure 1b Shown is a schematic diagram of the main power circuit structure of the existing motor controller, such as Figure 1a as well as Figure 1b As shown, with the development of permanent magnet motor and control technology, there are more and more vehicle applications using permanent magnet motor drive mode (hybrid or pure electric output). The permanent magnet motor drive mode is mainly controlled by the motor controller to drive the permanent magnet motor for drive output. The permanent magnet motor controller is mainly composed of a DSP control circuit and a power circuit. It sends control signals to the IGBT and other power switching elements of the main power circuit through the DSP control circuit board to realize the drive control of the permanent magnet motor. The main power ...
