This paper presents a bridgeless-single ended primary inductance converter (BL-SEPIC) fed brushless DC (BLDC) motor drive for low power household applications. The speed of the BLDC motor is controlled by adjusting the DC link voltage of the VSI feeding a BLDC motor. The VSI feeding BLDC motor is used for achieving an electronic commutation of the BLDC motor and operates in a low frequency switching...
This paper presents a single stage isolated Cuk converter for low power light emitting diode (LED) driver systems. An opto-couplerless feedback control using primary-side regulation technology is presented in discontinuous conduction mode (DCM). A complete analysis of the converter is carried out using pulse-frequency modulation technique. The primary focus of this work is to develop a cost effective...
