This paper presents an induction heater (IH) with power factor correction (PFC) for domestic induction heating applications. A half bridge voltage fed series resonant inverter (VFSRI) based IH is fed from the front end PFC corrected zeta converter. The PFC-zeta converter operating in continuous inductor conduction mode (CICM) is used to regulate the DC link voltage. The switch current stress of PFC-zeta...
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...
The aim of this paper is to introduce power quality added function to the standard Vienna rectifier in order to compensate reactive power and to cancel current-type harmonics drawn by nonlinear loads connected to the same point of common coupling. A theoretical investigation that demonstrates the ability of such topology to compensate harmonics and limited reactive power is first presented. Then,...
This paper deals with a single-stage PFC (Power Factor Corrected) buck-boost converter based low power LED (Light Emitting Diode) lamp driver for general purpose lighting. In the proposed circuit, a buck-boost converter is operated in CCM (Continuous Conduction Mode) with PSCR (Primary Sensing Current Regulation) using feed forward current control scheme to improve power quality at universal AC mains...
