Abstract :
Recently, the researchers concentrate on the
development of DC-DC converters with high voltage
conversion ratio suitable for applications in
nonconventional energy system based power generation.
Two categories of DC-DC conversion schemes are
available; transformer-based (isolated) and
transformerless (non-isolated) configurations. Due to
certain drawbacks present in transformer-based DC-DC
conversion scheme, the non-isolated DC-DC converters
are mostly preferred for applications that involve power
generation using renewable energy sources. There are
certain simple configured non-isolated high gain DC-DC
conversion schemes with single control switch. This paper
proposes the steady state analysis of a non-isolated highgain single-switch DC-DC conversion scheme based on
single-ended primary-inductor converter (SEPIC)
topology with DC motor load. The proposed converter is
operated in continuous conduction mode. The simulation
analysis of the proposed SEPIC converter feeding a DC
shunt motor is carried out using MATLAB / SIMULINK
software tool. The no-load characteristics of the motor
such as speed, torque, and armature current are
validated by changing the converter output voltage
through duty factor variation of the switch.
