An established technique to maximize the output power of photovoltaic (PV) systems, thereby raising ‎the efficiency of renewable energy systems, is maximum power point tracking (MPPT). This paper ‎focuses on designing and controlling a boost converter for MPPT in a PV system to calculate the ‎appropriate range of output resistance, minimum inductance, input capacitor, and output capacitor for ‎the boost converter so that the maximum PV output is achieved and the decision speed of MOSFET ‎switching is obtained by adopting the combined resistance-predictive method. The simulation results ‎demonstrate the efficacy of the proposed method in attaining these objectives. The suggested technique ‎can effectively track the maximum power point (MPP) within a broad spectrum of solar radiation while ‎ensuring that the duty cycle remains within its permissible range.‎
