Abstract :
In recent years DC-DC converters have
found wide applications in industry which have taken a
special place with the expansion of the use of renewable
energy sources. DC-DC converters with step-down/stepup voltage are required in many applications like
electronic products, fuel cell systems, battery powered
systems, portable devices, light emitting diode (LED)
and electric vehicle. Therefore converters with high
voltage con-version ratio, high efficiency, low cost and
small size are needed. A switched inductor based
converter achieves, high voltage ratio for applications
that needs of high voltage, improves the effi-ciency and
reduces voltage stress. The Switched Inductor based
Transformerless Buck-Boost converter has continuous
input and output current. The output voltage ripple of
this converter is low and the voltage stress across switch
and diodes are slight and lower than the converters
output voltage. Results are obtained by simulating the
converter in MATLAB/ SIMULINK R2021b. The
simulation results shows that the Switched Inductor
based Transformerless Buck-Boost converter has high
voltage gain and achieves a peak efficiency
