Comparison of Power and Efficiency in Synchronous Converter with INC and P&O MPPT Algorithm

Abstract

A maximum power point tracking (MPPT) algorithm optimizes the power output of a solar panel by continuously adjusting the duty cycle based on real-time voltage and current measurements. This process ensures the system operates at the panel’s maximum power point without overloading it. However, maintaining converter stability and fast convergence under varying solar irradiance conditions poses a challenge, as output power can oscillate before stabilizing at the maximum power point. Traditional non-synchronous converters use fast-switching diodes to block reverse current, but in high-current applications, power loss increases significantly due to the diode’s internal resistance. Synchronous converters, by using the MOSFET’s intrinsic body diode, address this issue and enhance efficiency. This paper focuses on comparing the performance and power conversion efficiency of the two converter types, highlighting the improvements in power extraction and efficiency at the maximum power point.
