FPGA based multi-sampling pulse compensation method with deadbeat control for single phase PWM inverter

A new approach of deadbeat control with multi-sampling pulse compensation method for single phase PWM inverter using FPGA based hardware controller is proposed. Using FPGA, 1 MHz multi-sampling between the carrier interval can be realized to improve the tracking accuracy of the inverter voltage to the reference. Control characteristic of the proposed deadbeat control method was verified through simulations and experiments with various digital control methods
