Abstract

The invention discloses a three-terminal voltage-stabilized compressor constant-current driving system, which is characterized in that: it mainly consists of a driving chip U1, a resistor R4, a capacitor C4, a diode D2, a resistor R5, a constant-current source circuit, and a three-terminal voltage-stabilizing circuit And drive circuit composition. The present invention adopts the driving chip U1 combined with the peripheral constant current source circuit and the driving circuit, which can reduce the current fluctuation range of the driving system of the present invention, and provide a stable working current for the compressor, thereby prolonging the service life of the compressor for one and a half years The above are suitable for promotion and application.

Description

technical field [0001] The invention relates to a driving system, in particular to a constant current driving system of a three-terminal voltage stabilizing compressor. Background technique [0002] A compressor is a driven fluid machine that converts low-pressure gas into high-pressure gas. It is the heart of the refrigeration system. Both refrigerators and air conditioners need compressors. At present, the current fluctuation range of the driving circuit used for the compressor is relatively large, which makes the operating current of the compressor not stable enough, thereby shortening the life of the compressor. The cost of replacing the compressor is relatively high, thus providing the cost of using the refrigerator and air conditioner. Contents of the invention [0003] The purpose of the present invention is to overcome the defect that the current fluctuation range of the driving circuit used for the compressor is relatively large, so that the operating current of ...
