We proposed the three phase active filter by controlling the ripple power based on the instantaneous AC line power detection. And we showed that the proposed system had many excellent features such as simple construction, high accuracy, high efficiency and so on.
In this paper, we apply this control principle to the single phase power line compensator such as active filter, reactive power compensator. In this case, we must control the instantaneous current waveform instead of ripple components of 2 axis quantities of three phase current or power. The proposed system can be easily constructed and controlled only by detecting the AC line side current and the DC side voltage of the PWM converter. The system has many functions such as a PWM converter, an active filter, a reactive power compensator at the same time without any modifications in addition to the above excellent features.
In this paper, we describe the proposed system comparing with the conventional one and confirm the feasibility of the system by simulation and experimental results.
