Abstract :
Enhancing the voltage ratio in a converter is a
leading aim to improve its performance. Regarding
this goal, a new topology of buck-boost converter is
introduced. DC-DC converters are essential devices in
many applications like UPS, solar energy, wind energy
batteries, where their output voltage being constant. The
converter offers a much higher voltage gain ratio in
comparison to its relevant high gain buck-boost
structures. The range of duty cycle has widened in this
converter without adopting any transformers or coupled
inductors in its configuration. The number of
components is quite a few. There- fore, this converter is
quite easy to be controlled. Furthermore, a common
electrical ground is provided between the input and
output ports. This has a high level of priority due to the
conviction that, when a converter lacks this feature,
another isolated device is required for controlling the
power switches. This would considerably increase the
costs of implementing such structures. As a result, their
practical usage in several applications is highly limited.
Hence, maintaining common electrical ground is another
feature that must be considered in devising a converter.
Hence, this structure is an appropriate choice to be
utilized in several industrial applications. Results are
obtained by simulating the system in
MATLAB/SIMULINK R2020b.
