This article presents the fuel cell electric vehicle (FCEV) power supply system configuration, and proposes a topology of high interleaved boost converter for cell. With thorough analysis operating principle converter, eight equivalent sub-circuits are described. According to waveforms inductor current, operation modes classified six kinds, including CCM (continuous conducting mode) DCM (discontinuous mode), uniform state-space averaged model in developed. Based on transfer function,...
This article proposes a novel topology of high power interleaved boost converter for fuel cell. With thorough analysis the operating principle converter, eight equivalent sub-circuits are described. According to waveforms inductor current, operation modes classified six kinds, including CCM (continuous conducting mode) and DCM (discontinuous mode), uniform state-space averaged model in developed. Based on transfer function, two-loop controllers designed, prototype 150 kW that is controlled...
Weakly coupled resonators (WCRs) predicated on the mode localization phenomenon have found widespread utility in topological design of high-performance sensors. However, pronounced non-linearity derived from loci veering around zero point imposes a significant constraint measurement range mode-localized This paper introduces novel single-port readout circuit aimed at realizing full-scale linear sensing for In our proposed methodology, we employ not only conventional frequency closed-loop...
High power DC/DC converter has become the essential part of distributed system in fuel cell powered electric vehicles and stationary systems. This paper proposes a topology high dual-phase boost for supply. The principle operating BOOST mode are analyzed thoroughly. A 150 KW was designed. adopted DSP-based fully digital dual-loop control. efficiency is over 97%, experimental results realized perfect effect
Most indoor substations adopt oil-immersed transformers as voltage transformation device. In multiple disadvantage conditions, the flammable gases formed form transformer oil may explode in room. Typical 220kV main room of substation was researched this paper. An correlation pressure relief area mail were presented based on CFD tool FLACS modeling general designing schemes State Grid Corporation China. This research be used reference technology for rooms substations.
