Abstract:

In this paper a novel four-leg interleaved DC-DC boost converter is proposed which is well suitable for fuel cell vehicles (FCV) application. The voltage stress of two switches of this converter is half of the conventional interleaved converters. Therefore, smaller and cheaper switches can be utilized. Also "on" state duration of the two of four switches are reduced in comparison with conventional converter. Furthermore, comparing the losses of the proposed converter to conventional one – which is used in ،Toyota Mirai 2015 – shows a significant loss reduction in full power range. The proposed converter is simulated within an FCV in urban and highway driving cycles using ADVISOR software. The results show that the average power loss of the converter is improved about 32% in urban cycle and about 17% in highway cycle comparing to conventional one.

A Quarantine DC/DC Converter using High- Frequency Unstructured LLC Resonant Converter for Fuel Cell Application

This paper suggests an isolated dc/dc converter using an unregulated LLC converter for fuel cell applications. The LLC converter operates as an isolated voltage amplifier with a constant voltage gain, and a nonisolated converter installed in the input stage regulates the output voltage under a wide variation of fuel cell stack voltage. By separating the functions, the unregulated LLC converter ...

High Step-Up Interleaved DC/DC Converter Using VM Cell for PV Applications

This work proposes a high step-up interleaved dc/dc topology utilizing a VM (voltage multiplier) cell suitable for PV applications. The VM cells D/C (Diode/Cap.) are cascaded among the phases to approach a high voltage gain. Besides, the voltage converting ratio of the presented structure can be improved by extending the VM cells and it also leads to drop in the normalized voltage stress throug...

Two Phase Interleaved Dc- Dc Converter

This paper presents a high-efficiency nonisolated interleaved dc–dc inductor boost converter with a common active clamp circuit. Interleaved boost converters are highly preferred as it reduces the ripple current. A boost converter is used to clamp the voltage stresses of all the switches in the interleaved converter which is caused by the leakage inductances. The leakage energies of the interle...
