A current control method for the utility interactive inverter based on multi-rate deadbeat control method with FPGA based hardware controller is verified for 100kHz carrier PWM inverter. As the distributed power systems spread, the requirement of the control accuracy for the utility interactive inverter becomes more precise. Deadbeat control is one method to ensure the output voltage or current matches to the references at the sampling instant, so adopting this control law to the utility interactive inverter, the response of the system is much improved with small LC filter component compared with the conventional PI control. A current control method for the utility interactive inverter based on multi-rate deadbeat control, single-rate deadbeat control and PI control were compared. Multi-rate deadbeat control improves the tracking accuracy to the reference compared with the conventional single-rate deadbeat control and PI control. The advantages and disadvantages are discussed through simulations and experiments.
