Abstract
Maximum Power Point Tracking (MPPT) is a method that can be used to optimize the electrical power output from solar panels. The performance of the MPPT method on solar panel systems can be influenced by many variables. One of them is the selection of a DC-DC power converter. DC-DC-DC Converter is a component that is used to optimize the performance of solar panels. Several types of DC-DC Converter are Buck, Buck-Boost, Single Ended Primary Inductance Converter (SEPIC), and CUK. Each converter has a different effect on solar panels output power. In order to observe and make a comprehensive analysis, simulations are performed through PSIM (Power Simulator) software on the performance of several DC-DC Converters that use Flower Pollination Algorithm (FPA) as the MPPT algorithm. Variables that observed are the output power characteristic, the response of the voltage-current ripple signal, and the accuracy of the converter in the process of reaching the maximum power point condition. As a result, CUK converter can obtain the highest value of solar panel output power, 145.02 W. A low ripple level with a stable power value response is entirely generated by CUK and SEPIC Converter. Overall, for this system, the CUK converter has better performance than the other converters.

Summary
The solar panel system has been widely used in various ways, especially in the realm of renewable energy sector power generation. One component that highly supports and improves the performance of solar panel systems is DC-DC converter. Elaborating on previous research, DC-DC Converter can increase the electrical output of solar panels no less than 5 % compared to the system without DC-DC Converter [1, 2]. DC-DC Converter is widely applied to large systems or as sub-systems with source and output systems in the form of DC electrical networks [3]. Some of the objectives of implementing DC-DC converter on solar panel electrical networks such as: optimizing the output of solar panel power, maintaining the output voltage of solar panels at a certain value range, or for other system applications [4, 5]. This research is intended to find out what type of converter has the best performance in solar panel optimization systems
