Abstract: This modular research aims to design and simulate an adaptive multilevel Boost Converter (MBC) that produces multiple output voltages. This is achieved by controlling and regulating the self-voltage balancing switch capacitors of the conventional Boost Converter BC-based MBC through a controlled single switch. In this paper, another improvement in 2N-1 capacitors and 2N-1 diodes is the structure of MBC. The main objective of the suggested design is to provide an ideal high voltage boost ratio using low power rating devices to reach a single voltage level at each step. The most significant features of MBC are a substantial boost gain at the limit value of duty cycle, running at a reliable continuous input current, no need for a transformer, and balanced output voltage, which permits working the MBC at a high switching frequency of 50kHz. MPPT was designed for a PV array that realized low input current ripples. The selected converter's principle is simulated under different conditions to prove that the estimated planned topology functions at its maximum appropriate voltage gain, with a high efficiency of 99.6% at a duty cycle of 49.6%, with a high voltage gain of 7.45 at the same duty cycle, the system was designed and simulated using MATLAB Simulink.
