On the power factor correction, there are three methods that the first is use of compensating capacitors, the second are correction of the fundamental power factor, distortion factor and total power factor by means of the variations of the turn on or off angles and the third method correct both power factors and efficiency by means of the circulation of the reactive power component. The purposes of this research are the basic analysis and experiment of the total power factor on the circulating a.c. chopper for example and can be applied to the power factor correction of another triple frequency sources. We are known that the total power factor can be correct from the zero value even in the case of the L. load to nearly the value of the R. load power factor.
