This paper presents supercapacitors and battery association methodology for ECCE Hybrid vehicle. ECCE is an experimental Hybrid Vehicle developed at L2ES Laboratory in collaboration with the Research Center in Electrical Engineering and Electronics in Belfort (CREEBEL) and other French partners. This test bench has currently lead-acid batteries with a rated voltage of 540 V, two motors each one coupled with one alternator. The alternators are feeding a DC-bus by rectifers. The main objective of this paper is to study the management of the energy provides by two supercapacitor packs. Each supercapacitors module is made of 108 cells with a maximum voltage of 270V. This experimental test bench is carried out for studies and innovating tests for the Hybrid Vehicle applications. The multi boost and multi full bridge converter topologies are studied to define the best topology for the embarked power management. The authors propose a good power management strategy by using the multi boost and the multi full bridge converter topologies. The experimental and simulation results of the two converter topologies are presented.

“…In [22,23,24,25], some zero-voltage and zero-current switching (ZVZCS) PSFB converters are proposed to remove circulating current and to extend ZVS range. In these converters, an auxiliary voltage source is introduced into the secondary side or primary side of the traditional converters, which makes the primary current decay to zero during the freewheeling interval.…”

Dual-half bridge (DHB) converter is a novel family of phaseshifted full-bridge (PSFB) converter, and it can obtain a significant improvement in conversion efficiency compared to the traditional PSFB converter. However, the main drawback of DHB converter is that only the energy stored in leakage inductor can be used to discharge the junction capacitors of switches. All switches tend to lose zero-voltage switching (ZVS) under light load conditions, which will significantly degrade efficiency. This paper proposes a simple and effective method to extend the ZVS range of DHB converter. By making the DHB converter operating in discontinuous conduction mode (DCM) and widening the dead-time, the energy stored in the magnetizing inductors of transformers can be used to discharge the junction capacitors. Without additional auxiliary components, the ZVS operation under light load conditions can be obtained. Experimental results confirm the validity of proposed method.

“…In these cases, the parallel capacitors discharge through the IGBT when it is turned on. This is the reason for the increase in switching losses and failure risk in IGBTs [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. The use of a high-value capacitor in parallel with the IGBT is restricted because of the capacitor discharge through the IGBT.…”

Abstract:In this study, a high-performance single-phase inverter arc welding machine is presented. Power control of the developed welding machine is realized with a high-frequency, phase-shifted full bridge (PSFB) pulse-width modulation (PWM) converter. The PSFB PWM converter operates with soft switching at no load and full load. There is no need to use a passive snubber in the converter. Welding machine control is implemented with a digital signal processor (DSP) and phase-shift PWM IC. By means of the DSP, advanced arc welding functions and protection features such as shortcircuit, over-current, and temperature protection are achieved. The current and voltage waveforms given are from an IGBT-based PSFB PWM arc welding machine operating at 75 kHz switching frequency and 160 A output current. The experimental results show that the proposed system has promising feasibility in industrial applications.
