Abstract-A new current control method based on the internal model principle in control theory is proposed. It introduces a sinusoidal internal model into the control system. It does not use any coordinate transformations. The method can be used for tracking an arbitrary number of harmonics: a dc component or fundamental frequency component signal. It is applied to a single-phase pulsewidth modulation inverter and active filter. The validity is confirmed by simulation and experimental results.

“…In active power filters for compensating harmonic currents, the three-phase voltage-source-type PWM inverter using such as IGBTs, IEGTs and IGCTs is often employed [1][2][3][4][5][6]. The voltage-source-type PWM inverter is also applied to divided power systems utilizing new forms of energy such as solar cells, fuel cells, and so on.…”

SUMMARYAn effective system control method is presented for applying a three-phase current-source PWM converter with a deadbeat controller to active power filters (APFs). In the shunt-type configuration, the APF is controlled such that the current drawn by the APF from the utility is equal to the current harmonics and reactive current required for the load. To attain the time-optimal response of the APF supply current, a two-dimensional deadbeat control scheme is applied to APF current control. Furthermore, in order to cancel both the delay in the two-dimensional deadbeat control scheme and the delay in DSP control strategy, an Adaptive Line Enhancer (ALE) is introduced in order to predict the desired value three sampling periods ahead. ALE has another function of bringing robustness to the deadbeat control system. Due to the ALE, settling time is made short in a transient state. On the other hand, total harmonic distortion (THD) of source currents can be minimized compared to the case where ideal identification of the controlled system can be made. The experimental results obtained from the DSP-based APF are also reported. The compensating ability of this APF is very high in accuracy and responsiveness although the modulation frequency is rather low.
