Based on a Novel Modular Converter, Modular Battery Management for SRM drives in Hybrid Vehicles

Abstract: In order to address environmental issues, the automotive industry is moving in a significant direction towards hybrid vehicles. One of its primary drive system options is a switching reluctance motor (SRM). This article designs a brand-new SRM converter topology. The innovative converter can manage battery energy and implement multi-level control. The battery control circuit is created in a modular manner, allowing the number of battery modules (BMs) to be chosen based on system needs. A hybrid vehicle's driving conditions are used to separate the converter's status into five states and conduct detailed analyses of each. Ultimately, the novel converter's simulation model and testing platform are constructed. The findings of the simulation and experiment confirm the viability of various working modes of the system's fault tolerance and reliability have been considerably enhanced by the innovative converter topology and the ability to individually regulate each BM.

Hardware in the loop modeling of T-type voltage source inverter for vehicle to grid applications

The grid-tied three-phase T-type voltage source inverter (T-type VSI) modeling process for residential battery charging stations is described in this paper. The primary goal is to create a HIL simulation model and control algorithm for the PLECS circuit simulator. This paper focused on the importance of the HIL simulation system in testing the control algorithm and power electronics. The hardware architecture of the system, the software tool, and the required modifications are described. Additionally, the proposed converter's simulation results are evaluated.

A non‐isolated switched inductor‐capacitor cell based multiple high voltage gain DC‐DC boost converter

AbstractIn this paper, a non‐isolated switched inductor cell integrated high step‐up voltage gain DC‐DC converter with a charge pump mechanism is discussed. The continuous conduction mode of the input current is a beneficial aspect of this converter, which is appropriate for electric vehicles, renewable energy, and LED applications. The proposed converter works in two distinct operating modes and provides a flexible range of voltage gain ratios. The performance and small‐signal modeling of the converter in continuous conduction mode are extensively investigated, and voltage gain calculations for the two operational modes are derived. The Markov technique is used to evaluate the converter reliability, component failure rates, and mean time to failures. The proposed converter is evaluated with the existing converters in terms of voltage, and current stress of each component, voltage gain, total component stress factor, component count, and reliability. The proposed converter's hardware prototype has been developed. To validate the theoretical calculations, the converter's simulation and experimental results are discussed. The converter has a maximum output voltage of 110 V and a switching frequency of 50 kHz. The converter's peak efficiency is 94.5%.
