Telos: enabling ultra-low power wireless research
- In IPSN
, 2005
"... Abstract — We present Telos, an ultra low power wireless sensor module (“mote”) for research and experimentation. Telos is the latest in a line of motes developed by UC Berkeley to enable wireless sensor network (WSN) research. It is a new mote design built from scratch based on expe-riences with pr ..."

Energy Saving Through Regenerative Braking in Diesel Locomotive with Super-capacitors
, 2012
"... ABSTRACT: The aim of this paper is to build an energy storage system for regenerative braking, with use of dc to dc converter, and testing rig to perform testing for dc drive with dc motor with the super capacitor bank against diesel locomotive (WDM2) regenerative braking profiles. A bank of was con ..."

. It was found that capacitor banks with a higher maximum voltage i.e. more cells in series were more efficient as there were lower input and output currents and most of losses were restricted to the converter.
High-efficiency Transformerless PV Inverter Circuits
, 2015
"... With worldwide growing demand for electric energy, there has been a great interest in exploring photovoltaic (PV) sources. For the PV generation system, the power converter is the most essential part for the efficiency and function performance. In recent years, there have been quite a few new transf ..."

High Efficiency Boost Converter with Three State Switching Cell
"... The boost converter with the three-state switching cell seems to be a good candidate for a dc-dc stage for non-isolated generators based on alternative energy sources. It provides a high voltage gain, a reduced voltage stress on transistors and limited input current ripples. In this paper the focus ..."

Instead of the conventional battery-based energy storage, this paper argues that the super capacitor buffering of solar energy (SOLARCAP) has the advantages of precise energy lifetime awareness, low maintenance, and operational robustness. By designing and developing a
Multi-Level Representation for the Control Design of a Super Capacitor Storage
"... Abstract. In this paper an average multi-level representation of power electronic converters is used to design a dynamic model of a Super Capacitor Bank for a microgrid application. A dedicated multi-level modeling is designed to quantify energy variations in storage elements (super capacitors, DC b ..."

We demonstrate that this model is sufficient to design the control system of the entire power storage system, meanwhile the super capacitors, the chopper and the grid connected converter. The proposed global model is simulated with the help of Matlab-SimulinkTM by considering
A Cell Balancing System Based on Charge Shuttling Method
