Abstract :
This article has surveyed some of the most important techniques used to generate the reference current for the shunt-type APF (active power filter). The GA-based approach is discussed in detail. Zero-crossing detection of one of the source voltages is sufficient, and the PLL may be removed. An ANN-based PI controller is added for faster buildup of the voltage across the capacitor. Faster control of the capacitor-voltage reduces the size of the capacitor and also improves the bandwidth of the controller. The proposed technique is simulated (in Simulink) and is also experimentally confirmed by developing a dSPACE1104-based prototype. With the availability of low-cost and high-speed processors, such computationally extensive methods are expected to be popular in the future.
