Gopalarathnam and Toliyat proposed a BLDC motor drive based on single-ended primary inductance converter (SEPIC), but it has higher losses in the VSI due to PWM switching and a greater number of current and voltage sensors which limits its applicability in low-cost applications. Singh and Singh proposed a Cuk converter powered BLDC motor drive with the concept of variable DC link voltage. This reduces switching losses in the VSI due to operating the fundamental switching frequency for electronic commutation of the BLDC motor and varying the speed by controlling the voltage on the VSI's DC bus. A Cuk converter CCM operation was used which requires three sensors and is not encouraged due to low cost and low power
