Embodiment Construction
[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0033] The embodiment of the present invention samples the three-phase voltage signal and the three-phase current signal within one cycle, and uses the three-phase voltage signal and the three-phase current signal as the first-level input quantity to obtain the second-level input quantity Ualfa after CLARK transformation and PARK transformation , Ubeta, Ugamma, and then obtain the PWM output signal for driving the switching device on the three-phase four-leg switching device through the following steps of the second-stage input quantity,
[0034] Step 1, determine the switch state vector by the working state of each group of bridge arms of the three-phase four bridge arms, and form the SVPWM control coordinate system by the obtained N switch state vectors. The specific method is to guide the upper bridge arm of each group of bridge arms to The off state of th...
