spacevector
Space vector modulation (SVM) is a method used to control three-phase inverters in AC motor drives and power electronics. It represents instantaneous line-to-line voltages as a single rotating vector in the two-dimensional alpha-beta (α–β) plane, derived from the three-phase quantities by a Clarke transform. The inverter’s DC-link voltage sets the vector’s magnitude, while switching states produce the desired output. SVM uses the six active switching states and two zero states within each switching period to synthesize the reference voltage.
The reference vector, which corresponds to the desired output, lies in one of six sectors formed by
Implementation typically relies on digital controllers such as DSPs or microcontrollers and requires careful handling of
