Abstract

This paper reports a Power Factor Correction (PFC) Canonical Switching Cell (CSC) converter for a sensor-less Brushless
DC (BLDC) motor drive system. CSC converter achieves continuous current in input and output, at the expense of reduced
number of passive components. The drive speed is adjusted using Voltage Mode control of the converter. Discontinuous
Inductor Current Mode (DICM) operation is used in this converter. This helps in attaining enhanced power quality (PQ)
at the ac supply mains and intrinsic (PFC). By Line Frequency Switching (LFS) of the Voltage Source Inverter (VSI)
switches, losses in the switches of the VSI are reduced. BLDC motor is operated in Sensor-less mode which prevents the
need for bulk and expensive Hall-Effect position sensors. Drive performance is assessed over a broad speed spectrum.
Unity Power Factor (UPF) is attained with enhanced power quality indicators within suggested thresholds of IEC 61000-3-2.
