Variable carrier frequency deadbeat control with hysteresis band using SoC-FPGA for utility interactive inverter

Abstract

Using SoC-FPGA based hardware controller, the real time gain calculation of deadbeat control can be realized, which result in the realization of variable carrier frequency control of PWM inverter for utility interactive system based on deadbeat control. Precise current control with adjustable hysteresis band was realized with the calculation capability of Soc-FPGA. It is verified that the control accuracy and the efficiency of the inverter can be adjustable.
