Variable carrier frequency deadbeat control for single phase and three phase utility interactive inverter using SoC-FPGA

Variable carrier frequency control of PWM inverter based on deadbeat control using SoC-FPGA based hardware controller was proposed. The inductor current was controlled using digital hysteresis method and the output current was controlled using deadbeat control with disturbance compensator. As the result, the control accuracy and the efficiency of the inverter can be adjustable with superior tracking accuracy to the reference current. Also extension to the three phase system were considered. Verifications were carried out through simulations and experiments.
