Light flicker, a phenomenon of annoying light intensity variation, caused by fluctuating electrical loads, has been a major concern for both industrial and residential customers. This paper presents a novel Dynamic Phase Controller (DPC) for flicker mitigation by compensating for variations in the rms line voltage during each half-cycle. IEC61000-4-15 flickermeter standard is employed to assess the flicker reduction provided by this controller. A virtual IEC flickermeter is then developed to perform the flicker measurement, and it demonstrates that the controller is capable of efficient flicker mitigation.
