Abstract :
In recent years, DC distribution systems are
gainingmore attention because of their high efficiency,
reliability com- pared to AC distribution systems.
Integration of lower voltage range renewable energy
sources into 400 V dc bus is one of the major
challenges to be faced by the power electronic converters.
Typical voltage ranges of a solar panel is around20-
30V . Conversion of these voltages to higher voltage
rangeby normal boost converters with high duty ratios
results in high voltage stresses and lesser efficiency.
Since, the output DC voltage from the photovoltaic panel
is very low, so a non- isolated interleaved high-gain
DC/DC converter with a voltage multiplier cell (VMC)
structure is presented. In order to achieve higher voltage
gain and to reduce the voltage stress of the switching
devices, the proposed high gain converter uses a two
phase interleaved technology combined with a boost unit
with a common ground, which has smaller input current
ripple and gainfeatures of high coefficient. This high gain
converter provides high voltage gain at low duty cycles
and reduces the voltagestresses on the switches effectively
when compared to the other boost converters. Results are
obtained by simulating the converter in MATLAB/
SIMULINK R2020b. The simulation results shows that
the proposed interleaved high gain converter improved
the gain, reduced the stresses in switching devices and
achieves a maximum operating efficiency of 85.
