Embodiment Construction
[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.
[0032] The existing method for switching the switching frequency of the motor is to switch the switching frequency immediately after receiving the switching frequency switching command, and the duty cycle before and after switching the switching frequency remains unchanged, which will cause a sudden change in the voltage action time before and after switching the switching frequency. , there is an instantaneous current impact, which in turn prod...
