| Abstract |
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 the proposed method, different
approaches were applied to derive the discrete model to
the utility voltage and the inverter voltage. As a result,
superior characteristics were derived with very small LC
filter component. Also to utilize the capability of FPGA
based hardware controller, all the control circuit for the
proposed current control method using voltage deadbeat
control and PLL control with quasi-dq transformation
are implemented in FPGA based hardware controller. The
design concept of the controller is also described, and the
advantages and the disadvantage are discussed through
simulations and experiments. |
