Modeling and Evaluation of Modified SEPIC Converter Fed BLDC Motor Drive

This paper illustrates the outline and assessment of high pick up non-separated dc-dc converter for sustainable power source applications with BLDC motor drive, by utilizing MATLAB simulink. High gain modified Single Ended Primary Inductor Converter (SEPIC) works under both CCM and DCM modes of operations. The output voltage of Modified SEPIC converter is more prominent than or not exactly or equivalent to its input voltage It act as a Voltage-doubler circuit for furnishing high voltage pick up with decreased voltage worry over the switches. To keep up a consistent output voltage closed loop control is required. This converter has low switch voltage and high proficiency. It is utilized for low input voltage and high power applications. This paper gives plan and investigation of Modified SEPIC converter for an Input voltage of 24V and a output of 48V with output power of 100W. Keywords: DC-DC converter, High gain modified SEPIC, voltage-doubler, BLDC.
