H02P 27/08 with pulse width modulation
Full Title
Arrangements or methods for the control of AC motors characterised by the kind of supply voltage (of two or more motors H02P5/00; of synchronous motors with electronic commutators H02P6/00; of DC motors H02P7/00; of stepping motors H02P8/00) > using variable-frequency supply voltage, e.g. inverter or converter supply voltage > using DC to AC converters or inverters (H02P27/05 takes precedence) > with pulse width modulation
