Single Phase SVPWM for Grid-Tied Inverter Based on d-q Synchronous Reference Frame Controller

摘要

The traditional pulse width modulation (PWM) technique has been superseded by space vector pulse width modulation (SVPWM) techniques, for digital implementation. In this paper, SVPWM of single phase half- bridge inverter based current control using the d-q synchronous reference frame is proposed. The results are applied in the current control of single phase inverter supplying resistive and inductive loads. Grid-tied single phase inverter for photovoltaic system applications is also discussed in this paper. The concept is validated by simulation in MATLAB.
