Abstract

A novel current fed isolated voltage multiplier converter (IVMC) exhibiting fast dynamics and high efficiency with seamless interfacing of low voltage PV panel with a high voltage DC bus is presented in the paper. The proposed converter exhibits interleaving for a quantifiable reduction in the input current ripple and input filter size while ensuring the superior performance of the maximum power point tracking (MPPT) controller. The low turn ratio of the high-frequency transformer incorporated into the IVMC allows for galvanic isolation along with lower leakage inductance. The distributed architecture of the IVMC facilitates a reduction in the voltage ripple across the multiplier capacitors and proportionally distributes the voltage gain among the different stages. Furthermore, it creates parallel conduction paths, which reduces the conduction losses in the devices and magnetic components. The scalability and modularity of the IVMC make it suitable for front-end PV applications where multiple front-end converters are interfaced to an intermediate DC bus for EV charging infrastructure. The performance of a hardware prototype of a PV fed IVMC under insolation variation is investigated through the MATLAB simulation environment and validated experimentally.
