Abstract: For industrial, electrical vehicles, drives, and grid applications ac-dc based inverters with power factor correction is considered as a key element to meet the power system firm regulatory rules. Among these dc-ac inverters, bridgeless converters play a vital role. In this paper, Bridgeless cuk and zeta converter-fed brushless dc (BLDC) motor drive is studied for power factor correction (PFC) and power quality improvement. The major objectives of this work are (i) dc bulk capacitance and inductance use is decreased, so that permanence film capacitors can be utilized, (ii) overall efficiency of BLDC drive system is improved due to decreased losses in the switches and conducting devices and (iii) guaranteed high or unity source power factor. The motor and source parameters are examined in this study for PFC using CUK and ZETA based dc-dc converters with MATLAB software. The work is compared with bridgeless ZETA, CUK.
Keywords: Bridgeless converter, ZETA dc-dc converter, CUK dc-dc converter, power factor correction.
