Abstract:
1. A synthetic space vector modulation (SVM) device for controlling a voltage source inverter (VSI) and load, or VSI and three phase motor, comprising: a variable frequency oscillator (VFO); a center-aligned pulse-train signal generator; a modulo-N counter, where N is an even integer equal to or greater than 6; and a three-phase time division multiplexer, wherein the VFO outputs a square wave to the modulo-N counter and a triangle wave of the same frequency to the center-aligned pulse-train signal generator, the outputs of the center-aligned pulse-train generator and the modulo-N counter are sent to the three-phase time division multiplexer, and after leaving the multiplexers, and before being sent to the VSI controller's load each positive and each negative output of the multiplexing phase is sent to a turn-on delay.
