Design of single-phase inverter controlled by DSC based on SVPWM technique

In practice, SVPWM technique has the advantages of high utilization rate of DC voltage, small loss of FFT, and easy-to-realize through Digital Controls, so this paper applied it to the single-phase inverter controlled by DSC (digital controller). By querying the data table, DSC generates single-phase SVPWM signals with dead-time control, which modulate H-bridge inverter to output AC through the high voltage driver chip-IR2113. The apply of the high-speed operation characteristic which make DSC be able to carry out PID feedback regulation and the eQEP (enhanced quadrature encoder pulse) which track and regulation the phase, make the system basically achieve the purpose of the instantaneous steady-state regulation of self-adaptive.
