Modelling of Four-Port Converter for Electric Vehicle Applications

Abstract

Multiport Converters (MPC) combine various renewable power sources through a single-stage power conversion. They offer the benefits of centralized control, excellent reliability, easy circuit configuration, small packaging, and cheap manufacturing cost & size. Due to its great efficiency and dependability, using a Multiport Converter to include renewable energy & energy storage into the bipolar dc bus is a preferable alternative. Full-bridge interleaving bidirectional buck/boost semi active rectifier with bi-polar output converter, a typical four-port converter (FPC), is specifically and in-depth examined in terms of operation principles, voltage and power relationship, port current ripples, soft switching performance, & control. The modelling and simulation studies of the FPC for PV, battery, and bipolar outputs in MATLAB/Simulink   suggested in this paper. Effects of duty ratio at different battery voltage and battery charging and discharging at various duty ratio verified. The power flow analysis done for different  intensities of PV and Battery voltage and load conditions.
