Electric motors account for 65 to 70 percent of industrial electrical energy consumption and approximately 57 percent of all electrical consumption worldwide. Therefore, Electronic designers of are now looking into maximizing the energy efficiency of a motor drive application using Power Factor Control (i.e. PFC). Utilizing an electronic drive to regulating the output speed of the motor for the mechanical load required, with the addition of Power Factor Control improves efficiency of the drive by correcting the out of phase voltage and current being used.

Classic Power Factor Control (i.e. PFC) circuits used in many drive applications have been the single boost topology. Recently, Interleaved Power Factor has gained much interest in the drive community. Each of these types of PFC topologies has distinct benefits, which will be described in Vincotech’s article in further detail.

As the industrial market looks to replace old inefficient motors, and new equipment manufactures try to make use of better variable speed motor solutions, high efficient drives will be the solution. Manufactures that offer motor drives with power factor control will be able to work with OEM customers meeting the needs of energy efficiency, low installation cost, and flexibility.
