The Study On The Application Of SVPWM Technology In The Modern Cascade Speed Regulation

With the increasingly serious energy crisis, this article focuses on applying the SVPWM control technology which have little harmonic, high utilization rate of DC voltage, strong regularity and easy-to-digital realization, to the modern chopper cascade speed control system of high efficiency energy-saving features.First,starting from an active three-phase voltage-type inverter and the basic principle of SVPWM control technology, this article builds the overall structure of the three-phase active inverter control which bases on SVPWM control strategy and uses SIMULINK dynamic simulation tool to achieve the simulation of SVPWM control algorithm for the passive inverters and active inverters. Based on this simulation results, I build the hardware experimental platform to prove the feasibility of applying the SVPWM technique to the modern cascade speed control system.
