Research of a New Type of Control Strategy of Active Power Filter and Its EMTP Simulatio

The paper proposed a new type of control strategy of voltage source APF,introduced design method of the control strategy in details,and gave block diagram of configuration and control of the(control) strategy.The control strategy used control method based on DC voltage control and reactive(current) feedback in order to control output current directly,which avoiding complex calculation for active(and reactive) power.EMTP-Scope view simulation result showed that the control strategy of voltage source APF could effectively compensate harmonic current and reactive current.
