The excessive input of phase‐advanced capacitors by customers has been posing a problem to date. To deal with this problem, the installation of phase‐advanced capacitors on the low‐voltage side was recommended, but it does not presently seem to have produced the expected effect. As a solution, a phase‐advanced rectifier circuit, integrated from rectifier circuit built‐in equipment and a phase‐advanced capacitor, is proposed and the effect of its introduction is discussed. This method is confirmed to be effective for the reduction of reactive power, because the receiving‐end voltage and current waveform distortion are improved. In particular, the number of capacitors introduced into the system under light load is reduced. © 2011 Wiley Periodicals, Inc.
