Application Research of SVPWM Technology in Chopper Internal-feedback Cascade Speed Regulation System

The SVPWM control technology which have little harmonic,high utilization rate of DC voltage,strong regularity and easy-to-digital realization was applied to the inner-feeding chopper cascade speed regulation system of high efficiency energy-saving features.From the three-phase voltage-type inverter and the basic principle of SVPWM control technology,the overall structure of the three-phase active inverter control was built which based on SVPWM control strategy and used SIMULINK dynamic simulation tool to achieve the simulation of SVPWM control algorithm for the active inverters.Based on this simulation results,the hardware experimental platform is built to prove the feasibility of applying the SVPWM technique to the inner-feeding chopper cascade speed regulation system.
