A variable dc link voltage of the voltage source inverter (VSI) feeding the BLDC motor is used for its speed control. This allows the operation of VSI in fundamental frequency switching to achieve an electronic commutation of the BLDC motor for reduced switching losses. A bridgeless configuration of an isolated Cuk converter is derived for the elimination of the front-end diode bridge rectifier to reduce conduction losses in it. The proposed PFC-based bridgeless isolated Cuk converter is designed to operate in discontinuous inductor current mode to achieve an inherent PFC at the ac mains. The proposed drive is controlled using a single voltage sensor to develop a cost-effective solution. The proposed drive is implemented to achieve a unity power factor at the ac mains for a wide range of speed control and supply voltages. An improved power quality is achieved at ac mains with power quality indices within the limits of the IEC 61000-3-2 standard.

A three-phase voltage-source inverter (VSI) is used for achieving an electronic commutation of the BLDC motor based on the rotor position as sensed by Hall-effect position sensors. A VSI-fed BLDC motor drive is generally supplied by a combination of a diode bridge rectifier (DBR) with a high value of smoothening dc link capacitor. This combination of DBR and dc link capacitor draws current only for a small duration when the instantaneous value of supply voltage is higher than the dc link voltage. Therefore, a peaky current is drawn from the ac mains, which has very high value of harmonic contents. The total harmonic distortion (THD) of such current is of the order of 60%– 80% which leads to a very poor power factor (PF) of the order of 0.6–0.7 at ac mains. Power factor correction (PFC) converters are used to avoid power quality problems at the ac mains and to meet the prescribed guidelines of IEC 61000-3-2 . The sensing requirement of this PFC converter plays amajor role in deciding the cost of the overall system. The required number of sensors for a PFC converter is primarily decided by its mode of operation of the PFC converter. Continuous inductor current mode (CICM) and discontinuous inductor current mode (DICM) are two modes of operation of the PFC converter. In CICM, or continuous conduction mode (CCM), the current in the inductor remains continuous in a switching period, whereas the current becomes discontinuous in a switching period for a PFC converter operating in DICM.

It has lower current stress on the PFC converter switch but requires three sensors (2-V, 1-C) for its operation. However, a single voltage sensor is used for a PFC converter operating in DICM using a voltage follower approach, but at the cost of high current stress on the PFC converter switche. Therefore, this mode of operation is suited for low-power applications. A conventional boost-PFC converter has been widely used for power quality improvements at ac mains. This converter has also been used at the front end of a VSI-fed BLDC motor for PFC at ac mains

Finally a voltage-fed, step-down inverter is used to drive the brushless DC motor. These capacitors are typically electrolytic and are physically large, expensive and failure prone, limiting the lifetime of the drive. Under certain conditions efficiency may be improved by the elimination of the boost stage

This maintains the required dc link voltage of the VSI and provides PFC at ac mains. The proposed PFC converter is designed to operate in DICM to act as an inherent power factor corrector. The dc link voltage of the VSI is controlled for adjusting the speed of the BLDC motor. The VSI feeding the BLDC motor is operated in a low frequency switching to achieve an electronic commutation of the BLDC motor for reduced switching losses. The proposed configuration uses a single voltage sensor to control the dc link voltage for the speed control of the BLDC motor.
