This paper presents Electrical model of solid oxide fuel cell (SOFC) for its applications of power generation. Based on the linearization of the V-I curve of Electrochemical-Electric-potential ECE model of planner anode-supported intermediate high temperature SOFC, Voltage-Source-Series-Resistance (VSSR) model for SOFC working in a stack is proposed, which is found suitable for equivalence to ECE...
Solid oxide fuel cells (SOFCs) are modular and flexible in relation to the fuel in use, and have the capability to be used for combined heat and power applications at high efficiency. Due to the advantages, SOFCs are emerging as an attractive energy generation option. As a generation resource, SOFCs could be used as a distributed one connected with a large power system and also could be planted in...
A critical-mode (CRM) operation has recently been used for low-to-medium power-level power factor correction (PFC) boost converter circuit. In theory, this circuit provides very good power factor and little distortion. However, in a real circuit, the input current of such operation suffers from significant input current distortion. In this paper, the phenomenon of input current distortion was analyzed,...
An InGaAs/InAlAs/InP HEMT with sub-50nm EBL gate has been developed for sub-millimeter wave (SMMW) power amplifier (PA) applications. In this paper, we report the device performance including high drain current, high gain, high breakdown voltage and scalability to large gate periphery, which are essential for achieving high output power at these frequencies. Excellent yield, process uniformity and...
We demonstrate 700-W fundamental mode beam from Yb-doped fiber laser operating at 1092 nm. Coiling 20-mum diameter and 0.06 NA core fiber into 15-cm diameter spool eliminates higher-order modes through distributed mode filtering
