Abstract

The invention provides a filter and an air conditioning unit. The filter comprises a main power board, an anti-surge circuit board, an LC filter circuit board and a low-pass filter circuit board. Theanti-surge circuit board, the LC filter circuit board and the low-pass filter circuit board are detachably installed on the main power board, and the anti-surge circuit board, the LC filter circuit board and the low-pass filter circuit board are electrically connected in sequence. The filter components with main functions of the filter are respectively formed on the anti-surge circuit board, the LC filter circuit board and the low-pass filter circuit board and are detachably arranged relative to the main power board, so that the functional components of the filter can be mounted and used immediately, the heat dissipation area is increased, and the filter can dissipate heat better. When the filter is used, the filtering scheme of the filter can be matched with filtering component boards with different parameters on the main power board, different filtering schemes can be flexibly matched for use, and the installation and the use of the filter are greatly facilitated.

Description

technical field [0001] The invention relates to the technical field of circuit components, in particular to a filter and an air conditioner unit. Background technique [0002] The converter filter is a filter circuit composed of inductance coils, capacitors, resistors and other components. It is a passive bidirectional network. One end of it is an AC incoming line or a DC incoming line, and the other end is a load. [0003] At present, the filter used in the converter is generally a filter board designed separately. The filter circuit and the anti-surge circuit are on the same board. When in use, the filter board is fixed inside the converter, and the three-phase AC is input through the incoming terminal. After passing through the anti-surge circuit and filter circuit, it is output at the outgoing terminal. When the filter is used, it needs to be fixed in the converter. The installation and disassembly are cumbersome, and the heat dissipation effect is not good. Various fil...
