To Improvement the power factor is very important. Because the costs are increased or reduced. To Improvement the power factor the higher the value it is necessary to buildings offices and industrial buildings or the fact that the industry needs real power. And reactive power source to operate. This paper presents the design and construction of reactive power factor control. Which amounted to 6 working order by the first sequence is divided into three three-phase electrical power system and three consecutive singles phase by active power different. first1 is reactive at 5 kVAr second 2 and third 3 are reactive at 2.5 kVAr forth 4 fifth 5 and sixth 6 precious marine active 0.83 kVAr control. the power factor controller that controls RG3-12 pay Oval active in various sequences. As a result when not equipped with reactive power compensation software to control the power factor. This makes the flow of the high and low Power Factor schedule. When equipped compensate reactive power source to power factor control. Single-phase motor 1 kW and light bulb 164-watt making the current decline of 14 amps rest 12 amps of the power factor increases from 0.5 to 0.929. When connected to three-phase motor with 2 kW 0.82.2 flow down from 2.360 rest 0.942 amps of power factor value up from 0.308 to 1.0.

The input power factor control of a carrier-based dipolar PWM  for matrix converters
The input power factor control of a carrier-based dipolar PWM for matrix converters

This paper presents the input power factor control of a modulation using a carrier-based dipolar for matrix converters by determining the optimum value of free parameters b and d in general solutions of the modulation matrix. The proposed PWM method is not only less complicated but can clearly show the coupling of the input power factor control from both active and reactive output power. The experimental results show that the proposed PWM method can control the conditioned input power factor set earlier
