Keywords:
PV, KY converter, Buck-boost converter, MPPT controller, DC-DC converterAbstract
With the abundance of solar energy, it can become a potential source of renewable energy that can replace fossil fuels. The utilization of renewable energy is marked by the emergence of solar panels. Solar panels themselves utilize a technology called photovoltaic. Currently, the use of PV has become increasingly widespread in Indonesian society, both in the commercial and residential sectors. Therefore, with the increasing number of PV users, there is a need to maximize PV power. In this research, the design of a configuration system combining KY and buck-boost converters is carried out to increase the input DC voltage to a higher output voltage level with better efficiency. The proposed converter is integrated with an MPPT controller using the Perturb and Observe (P&O) method to detect disturbances in PV voltage periodically by varying the duty cycle to obtain optimal PV power. The research results show that the combined KY and buck-boost converter system has a fast and continuous system response to reach a steady state of 0.06 seconds. The system performs optimally using the MPPT controller, with an efficiency of 90.21% and a maximum power output of 881.29 Watts at a load voltage of 311 V.
