Design and analysis of high-gain DC–DC chopper topologies for PV-fed BLDC motor drive system

Purpose Switching power converters for photovoltaic (PV) applications with high gain are rapidly expanding. To obtain better voltage gain, low switch stress, ripple and cost-effective converters, researchers developing several topologies. Design/methodology/approach It was decided to use the particle swarm optimization approach this system in order compute precise PI controller parameters under steady state dynamic changing circumstances. A high-gain q- ZS boost converter is used as an intermittent between a PV brushless direct current (BLDC) motor attain maximum point tracking, which also reduces torque ripples. MATLAB/Simulink environment has been build test positive output quadratic (PQBHGC)-1, PQBHGC-8, PQBHGC-4 PQBHGC-3 topologies analyse their effectiveness PV-driven BLDC applications. The simulation results show that topology effective comparison other HG cell DC–DC terms of efficiency, reduced ripples, etc. most suitable Findings have showed gives performance minimum 2V 0.4A eventually ripples motor. Also, efficiency suggested PV-based best 99%. Originality/value This study first its kind comparing different PQBHGC-1, suggests
