Abstract :
A voltage space vector PWM algorithm for a dynamic voltage restorer (DVR) based on a 3-dimensional αβ0 voltage space is described. The switching strategy is applicable to the control of 3-phase 4-wire inverter systems such as the split-capacitor PWM inverter and the 4-leg PWM inverter. Compared to the conventional voltage space vector PWM method, it controls αβ0 components of the terminal voltages instantaneously. The control algorithm was verified by simulation. Experimental results for a 3 kW DVR system using a split-capacitor PWM inverter are presented to validate the simulation results
