<p>A novel active power line conditioner (34) is disclosed. The apparatus includes a parallel inverter (30), with a dc-link, coupled to an output line. The parallel inverter (30) is controlled by a parallel inverter controller (40) which forces the parallel inverter (30) to act as a variable capacitor or inductor. The parallel inverter controller (40) identifies and feeds-forward a desired phase shift value between an active power line conditioner voltage input signal and an active power line conditioner voltage input signal. Utilization of the desired phase shift value results in voltage control of the dc-link of the parallel inverter (30). The parallel inverter controller (40) also produces a tuning capacitance current reference signal which reduces voltage magnitude errors of the output voltage.</p> |
