A novel approach to design of a power factor

This study describes a novel approach to design of a power factor correction (PFC) and total harmonic distortion (THD) reduction-based brushless DC (BLDC) motor drive. The drive was designed to Typically, power factor correction equipment is not required for VSI systems. More information can be found in IEC/TR 6 [3]. For LCI drives, the power factor is dependent on the operation point and the way the system is designed. The network power factor is proportional to the ratio of motor and network voltage.ADJUSTABLE SPEED DRIVE SYSTEM COMPARISON VSI
