Abstract

A new strategy for adaptive DC voltage control of an active power line conditioner (APLC) is proposed in this paper. The APLC is composed of a full-bridge inverter of which the DC voltage is supplied by a capacitor rather than a DC power supply. The relationships of the current slopes are discussed to determine the level of the DC voltage of the capacitor. By measuring the peak slope of the command for the compensating current, an optimal value for the reference DC voltage can be set based to produce an undistorted input current with a minimum switching loss. Experiments show satisfactory results for the APLC to operate under the proposed control method.
