Abstract—This paper proposes a novel, simple reactive power

control strategy for the active load balancer (ALB) in three-phase

four-wire distribution systems. The proposed reactive power

control strategy is applicable for adjustment of the sourceside

power factor under the balanced load condition. Only

DC capacitor voltage control is used in the proposed control

strategy. Therefore, the calculation blocks of the active and

reactive components of the load currents are not necessary.

The authors, thus, offer the simplest control strategy to control

reactive power under the balanced load condition on three-phase

four-wire distribution feeders. The basic principle of DC capacitor

voltage control based reactive power control strategy is discussed

in detail, and then confirmed by digital computer simulation.

A prototype experimental system was constructed and tested.

Experimental results demonstrate that balanced source currents

with reactive power control are achieved on three-phase four-wire

distribution feeders. These experimental results also demonstrate

that controlling the reactive power reduces the required power

rating of the ALB compared to that of the existing control

strategy, which achieves balanced source currents with unity

power factor.
