Abstract

The invention discloses a drive control circuit, a drive control method, a circuit board and an air conditioner. The drive control circuit comprises a first drive circuit, a switch assembly and a second drive circuit. By setting the second drive circuit, when the connection mode of a three-phase winding is switched, the second driving circuit can provide a second driving voltage for the three-phase winding in the switching process of the connection state of the three-phase winding to simulate the voltage environment where a first switch group and a second switch group are located in the switching process; therefore, when the connection mode is switched, even if the first switch group or the second switch group changes the on-off state, a motor still operates normally, the non-stop switching of the connection mode of the three-phase winding of the motor can be realized, and the normal operation of the compressor is not influenced.

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, an air conditioner and a storage medium. Background technique [0002] The inverter compressors of the existing inverter air conditioners mostly use permanent magnet motors as the driving motors. Due to the influence of the operation requirements of the inverter air conditioners, the three-phase windings of the permanent magnet motors usually need to be switched between star connection and delta connection. Generally speaking, it is The purpose of switching the connection mode is realized by controlling the switch device. However, most of the existing switching devices are mechanical, and it takes a certain amount of time to complete the closing or opening action. When using the existing scheme to switch the connection mode, the permanent magnet motor needs to be stopped for a short time, which aff...
