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 presice. As the carrier frequency of the PWM inverter gradually become higher range,...

Progress of FPGA technology makes it possible to include the software macro CPU core into the FPGA chip, a high flexibility can be realized for the construction of the control processor in power electronics application. In the proposed method, all the control system is implemented in one FPGA chip. Complicated...
A new current control method for the utility interactive inverter based on multi-rate deadbeat control with FPGA based hardware controller is proposed. Multi-rate deadbeat control improves the tracking accuracy to the reference compared with the conventional single rate deadbeat control. As a result, superior characteristics were derived with very small LC filter component. Also to utilize the capability...
A new approach for real time digital feedback control of single phase and three phase PWM inverter is proposed, in which a quasi multirate deadbeat control combined with variable sampling method using FPGA based hardware controller. It was reported that the deadbeat control method with FPGA based hardware controller had the very good transient response for various loads, but these reports were mainly...
A new current control method for the utility interactive inverter based on deadbeat control with FPGA based hardware controller is proposed. In the utility interactive system, the utility line voltage should be included in the system model, so the procedure to derive the discrete time system model is the key point to achieve the accurate control characteristics.

In this paper, five kinds of real time digital feedback control method for the PWM inverter with FPGA (filed programmable gate array) based hardware controller are compared for a low carrier-frequency PWM inverter system. It was reported that the deadbeat control method with FPGA based hardware controller had the very good transient response for various loads, but these reports were mainly focused...
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...
