Abstract

The energy crisis and health hazards expanding the interest on the sustainable sources for power production. Solar
based modules are utilized to collect solar energy. Meanwhile, EV bikes, autos and vehicles have become more
popular. Battery charging in EV is the important process. DC-DC converters are utilized to interface the
Photovoltaic source to the battery. A non-isolated (NI) DC-DC buck-boost converter has been employed as a
maximum power point tracking (MPPT) system to derive the photovoltaic power present. The MPPT control is
utilized to extricate the greatest power available from the photovoltaic source. The MPPT gets the solar irradiation
and solar cell temperature as contributions to decide the optimized duty cycle to acquire maximum power. In this
work, a non-isolated buck-boost converter is utilized as MPP tracker for battery charging applications. The
performance of the converter is simulated and validated through the experimental results.
