Embodiment Construction

[0027] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] In this embodiment, in order to solve the problem of air-conditioning products in the development and testing stage, it is necessary to replace the compressor many times and adjust the experimental working conditions of the air conditioner to meet the performance test requirements of the inverter circuit. The resulting test is difficult and the boundary conditions are not easy. To achieve the problem, creatively proposed a method of using a set of compressor simulation circuit to replace the actual compressor product in the performance test process of the inverter circuit, by changing the parameters of the components in the compressor simulation circuit, it can be conveniently Obtaining different loads not only satisfies various test requirements of the inverter circuit, but also avoids the process of replacing the compressor and reduces...

Abstract

The invention discloses a performance testing method and a testing device of an inverter circuit. Inductors and resistors are used to simulate a three-phase winding of a compressor, and a set of compressor analog circuits is designed; the compressor analog circuits are used as loads of the inverter circuit and connected to an alternating current output side of the inverter circuit; parameter values of the inductors and the resistors in the compressor analog circuits are changed to obtain different loads; and relevant parameters of the inverter circuit under different loads are detected to finish the performance testing of the inverter circuit. According to characteristics of an air condition compressor, the set of compressor analog circuits is designed to replace an actual compressor, used as the loads of the inverter circuit and applied to the performance testing process of the inverter circuit so that troubles that the compressor is required to be installed and replaced according to traditional test methods are solved, different loads can be conveniently obtained by changing parameters of devices in the compressor analog circuits, and performance testing requirements of the inverter circuit under different loads can be met.

Description

technical field [0001] The invention belongs to the technical field of electronic circuit testing, and in particular relates to a performance parameter testing method and testing device proposed for an inverter circuit used to drive an outdoor compressor in an air conditioner product. Background technique [0002] With the gradual warming of the earth's climate and the continuous improvement of people's living standards, air-conditioning products have gradually entered thousands of households and are widely used. Existing air-conditioning products generally include two parts: an indoor unit and an outdoor unit. Among them, the compressor installed in the outdoor unit can be said to be the power core of the entire air conditioner refrigeration system, and plays a role in the refrigeration circuit of the air conditioner. The role of the agent, and achieve the effect of refrigeration through heat conversion. [0003] In the circuit design of the outdoor unit of the air conditi...
