Advantages and Disadvantages of Bldc Motor - 863 PWM switching and a higher number of current and voltage sensors, which limits its applicability in low-cost applications. Singh and Singh proposed a BLDC motor drive powered by a Cuk converter with the concept of variable DC link voltage. This reduces switching losses in VSI due to the fundamental operation of the switching frequency for electronic switching of the BLDC motor and variation of speed by controlling the voltage on the DC bus of the VSI. A CCM operation of the Cuk converter was used, which requires three sensors and is not encouraged due to its low cost and low consumption.
