Dual input dual output power converter with one‐step‐ahead control for hybrid electric vehicle applications

Abstract

The rapid conversion of automotive accessory loads to the electrical domain demands a power converter to interface between the on-board source and storage units with the accessories. This study proposes a simplified structure of dual input dual output (DIDO) with single-stage power conversion for hybrid electric vehicle accessory applications. The topology is synthesised using pulsating source cells. The generic switch model-based DIDO is realised with power switches based on switch realisation technique. Steady-state and equivalent circuit models describing the converter structure are presented. Numerical simulations were performed with the state-space averaged mathematical model. A one-step-ahead controller is used for inductor current control in conjunction with a mode selection logic to utilise its operating modes based on the availability of the sources and its protection. The performance of the proposed converter and its associated control scheme under steadystate, transient conditions are corroborated by simulation and experimental results.

SiC switch‐based isolated DC‐DC converter for simultaneous charging of Li‐ion batteries of different voltage ratings for low‐ and medium‐power electric vehicle battery charging application

“…Santhosh and Govindaraju 23 have proposed a dual‐input dual‐output nonisolated converter for EV accessory applications. The proposed converter has been derived from the conventional boost converter and uses four switches, one diode, one inductor, and two capacitors.…”

A Multifunctional Non-Isolated Dual Input-Dual Output Converter for Electric Vehicle Applications

“…Fully directional universal dc/dc converter [25] operates as a SISO converter. A dual input dual output converter suitable for the hybrid electric vehicle is proposed [26]. It has the basic disadvantage of battery power not being boosted across the load.…”

Off‐board electric vehicle battery charger using PV array

“…Ever increasing effects of green house gases from the conventional IC engines lead to environmental concerns. This paved to the booming of pollution free electric vehicles (EVs) in the automobile industry [1][2][3]. However, EV battery charging from the utility grid increases the load demand on the grid and eventually increases the electricity bills to the EV owners which necessitate the use of alternate energy sources [4,5].…”
