Variable carrier deadbeat control with digital hysteresis method using SoC-FPGA for utility interactive inverter

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 disturbancecompensator. As the result, the control accuracy and the efficiency of the inverter can be adjustable with superior tracking accuracy to the reference current. Verifications were carried out through simulations and experiments.
