An assembling capacitor, a multilevel inverter and applications of the assembling capacitor

Abstract

The invention particularly relates to an assembling capacitor, an inverter including the assembling capacitor and applications of the assembling capacitor in the inverter. The assembling capacitor includes a container; a plurality of capacitors are arranged in the container; the plurality of capacitors are connected in series, in parallel, or in a series and parallel hybrid manner; and in both terminals of the assembling capacitor composed in the above-described manner, and a common terminal of partial capacitors, at least a first pin is led out outwardly from each terminal point. The connection among the individual capacitors is completed inside the container, and only the connection of the first pin of a capacitor and a terminal is needed during wiring; the wiring is simple, and the installation is easy; for two capacitors which are connected to a common terminal, the connection of two capacitors with the terminal can be achieved via the first pin of the common terminal, reducing the number of terminals, and further reducing the area occupied.

Description

technical field [0001] The invention relates to a capacitor, in particular to an aggregated capacitor, an inverter including the aggregated capacitor and the application of the aggregated capacitor in the inverter. Background technique [0002] Capacitors have the functions of energy storage and filtering, and are widely used in the field of electrotechnical technology. In applications, it is often necessary to connect multiple capacitors in series or in parallel or in a mixed manner of series and parallel, and then connect the terminals of some capacitors with other Component connections. When making a circuit board, usually each capacitor is connected to the terminal separately, such as figure 1 As shown, this method has a large number of terminals and occupies a large area; or after connecting the capacitor, connect its common and non-common terminals to the terminals, as shown in figure 2 As shown, this method has complex wiring and difficult installation.

AI Technical Summary

Problems solved by technology

When wiring, ordinary absorbing capacitors cannot be installed normally. It is necessary to use a capacitor with custom pins, or to use one foot of the absorbing capacitor. It is also necessary to install the capacitor face to face, which occupies a large area.
