The invention discloses an electrolytic capacitor motor driving method, device, electronic equipment and storage medium. In the present invention, according to the real-time rotational speed and the real-time angle of the rotor of the electrolytic capacitor motor, the given current of the q-axis and the d-axis of the electrolytic capacitor motor is calculated, and then according to the real-time current and the given current corresponding to the q-axis and the d-axis respectively, Determine the respective given voltages, so that the control of the inverter can be realized by controlling the given voltages of the q-axis and d-axis and the real-time angle of the motor rotor without electrolytic capacitors, so that the inverter can be transformed into The pulse width modulation wave drives the electrolytic capacitor motor to work. Through the above electrolytic capacitor motor driving method, the rotor speed pulsation and the input current peak value during the operation of the electrolytic capacitor motor can be effectively reduced, thereby greatly improving the reliability and stability of the electrolytic capacitor motor operation. Capacitor motors can be properly controlled as needed.
Description
technical field [0001] The invention relates to the technical field of motor control, in particular to a driving method, device, electronic equipment and storage medium for a non-electrolytic capacitor motor. Background technique [0002] In the single-phase AC power AC-DC-AC power conversion system of the traditional household air conditioner motor driver, the DC bus capacitor, such as an electrolytic capacitor, acts as an energy storage unit and provides sufficient input power for the motor. Therefore, in order to meet the above Need, the DC bus capacitor usually needs hundreds or thousands of uF (microfarads). However, the service life of electrolytic capacitors is greatly affected by temperature, especially in high temperature environments, and the compressors of refrigeration or heating electromechanical products such as air conditioners need to be placed in outdoor high temperature environments for a long time, so the electrolytic capacitors on the bus side The lifesp...
