Abstract

The invention discloses a drive circuit and an air conditioner. The drive circuit comprises a main control unit, a drive unit, a first communication unit, a second communication unit, a third communication unit, and a fourth communication unit. The first communication unit is connected with a first output interface of the main control unit and a first input interface of the drive unit through a first resistor, the second communication unit is connected with a second output interface of the main control unit and a second input interface of the driving unit through a second resistor, the third communication unit is connected with a second input interface of the main control unit and a second output interface of the drive unit through a third resistor, and the fourth communication unit is connected with a first input interface of the main control unit and a first output interface of the drive unit through a fourth resistor. Therefore, the drive unit is externally arranged, the productioncost is reduced, and the real-time state of a fan motor is monitored in real time.

Description

technical field [0001] The present application relates to the field of drive circuits, and more specifically, to a drive circuit and an air conditioner. Background technique [0002] In the field of air conditioning, the drive circuit is a commonly used circuit, mainly used to control the fan motor in the air conditioner. The current indoor fan of the air conditioner mostly uses a DC brushless motor, and the DC brushless motor is usually driven by a built-in drive unit. circuit driven. [0003] However, the built-in drive motor in the prior art has the following characteristics: [0004] Most of the DC motors used by air-conditioning manufacturers in the industry are built-in motors in the drive unit. Air-conditioning manufacturers only need to continuously adjust the duty cycle to control the speed. The control is relatively simple; however, the disadvantages of this built-in drive motor are also obvious, such as high cost and low efficiency. ; At the same time, the built...
