Example Embodiment
[0027] see figure 1 , the hybrid active power filter of the present invention includes an active power filter, a passive power filter, a harmonic current injection branch and a PWM rectifier, and the output of the active power filter is filtered by the output filter and then isolated The primary side of the transformer and the secondary side of the isolation transformer are connected in parallel with the fundamental wave series resonant circuit part of the harmonic current injection branch, and then connected in series with the injection capacitor of the harmonic current injection branch, and then merged into the power grid with the passive filter. The DC side of the source power filter is powered by a PWM rectifier.
[0028] When the passive filter part of the hybrid active power filter compensates the reactive power with a larger capacity, the fundamental impedance of the PF is small, and a large fundamental reactive current flows into the PF. At this time, since the series...
