Simulation for SVPWM inverter-Smith single-phase motor speed control

摘要

The transient performance of Smith single phase motor supplied by the single phase SVPWM voltage source inverter is studied emphatically. And then, voltage space vector of the single phase whole-bridge inverter is analyzed and the SVPWM whose control algorithm is deduced. Meanwhile, a transient mathematical model for the Smith single phase motor is developed. Moreover, a simulation model of variable frequency speed control system of single phase SVPWM inverter-Smith single phase motor is built by MATLAB/SIMULINK. Finally, by the simulation calculated to the actual case, the result is consistent with the theoretical analysis. Thus, it would be of a certain practical significance and reference value in the design of SVPWM inverter and speed control system of tri-winding single-phase condenser motor.
