Analysis and Design of an LC Parallel-Resonant DC–DC Converter for a Fuel Cell Used in an Electrical Vehicle

Abstract

In this paper, the design methodology of a parallel-resonant [Formula: see text] converter for fuel cell applications in the electric vehicle is proposed in order to achieve high efficiency. Although the converter is unidirectional, it is interposed between the fuel cell and the DC link. Additionally, the converter is made up of two full bridges, an [Formula: see text] resonant filter and a planar transformer. The use of a high-frequency transformer enables to minimize the converter size and the weight, to produce a higher voltage in the secondary side from an input voltage (fuel cell) and to isolate the full bridges. Furthermore, the rectifier diodes operate with a zero-current switching. Therefore, an experimental converter prototype has been designed, simulated, built and tested in the laboratory. Finally, a prototype having 30[Formula: see text]V as an input and 150[Formula: see text]V as an output with 500[Formula: see text]W is designed to demonstrate and analyze the proposed converter.

A Hybrid Intelligent Controller for Extended-Range Electric Vehicles

“…Authors in [20][21][22][23] describe how the acceleration and deceleration patterns of drivers affect the velocity control of EVs. Traffic and road conditions are given to the driver in order to be able to regulate the use of the accelerator and brake pedal [24][25][26][27][28][29][30].…”

“…In the present paper, the converters are analyzed from a systemic point of view, i.e., studying their performance in relation to the power distribution system. More information on DC-DC converters can be found in [28][29][30]. Their datasheets [25] include their efficiency curves as a function of the output current for different input voltages.…”

“…The fuel cell output voltage is low and cannot directly drive the car motor, which requires a high DC bus voltage (e.g., 400 V) [4]. Therefore, in order to provide a stable output voltage to the load, the DC-DC converter with high gain, wide voltage input range and fast dynamic response speed should be used in fuel cell vehicles [5][6][7][8].…”
