Study on Algorithm of Active Power Filter Based on Single Chip Computer

The control of Active Power Filter(APF) is very important to its performance.The control of APF is the separation technique of command current,and algorithm application.The algorithm of detect command current and the affect to the performance of APF is discussed for the harmonics detection more efficiently and accurately.The property of the APF will be improved by compensation of odd harmonic component and choosing sampling point location reasonably.
