Problems solved by technology

The driving motor of the compressor is generally a permanent magnet synchronous motor. Since the voltage of the power supply is generally fixed and limited by the DC bus voltage, the compressor is prone to voltage saturation under high load conditions and enters the field weakening control in advance, making the operation of the motor Efficiency drops

Abstract

The embodiment of the invention discloses a drive control circuit, a drive control method, a circuit board and an air conditioner, and the drive control circuit is connected with a first power module and a second power module at the two ends of an open winding motor, and the second power module is connected with an energy storage module. The controller sends control signals to the first power module and the second power module according to the electric quantity of the energy storage module to change the working state of the driving control circuit, so that electric energy can flow bidirectionally when the motor runs, the energy storage module can supply power to the open winding motor under the condition of sufficient energy, the running voltage of the motor is improved, and the service life of the motor is prolonged. The operation efficiency of the motor is improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a drive control circuit, a drive control method, a circuit board and an air conditioner. Background technique [0002] Air conditioners are household appliances commonly used in people's daily life. Compressors are an important component of air conditioners. The energy consumption of compressors accounts for a large proportion of the total energy consumption of air conditioners. Therefore, improving the efficiency of the compressor has a significant effect on improving the overall energy efficiency of the air conditioner. The drive motor of the compressor is generally a permanent magnet synchronous motor. Since the voltage of the power supply is generally fixed and limited by the DC bus voltage, the compressor is prone to voltage saturation under high load conditions and enters the field weakening control in advance, which makes the motor run. Efficiency drops. ...
