A six legs buck-boost interleaved converter for KERS application

2020

This paper addresses the design of a bi-directional DC/DC power converter to interface a supercapacitor bank and a motor-generator unit. The design is based on an interleaved six legs topology in which the current is shared among six inductors to minimize their weight and cost, allowing, besides, a low switching frequency to lessen switching losses. The converter is conceived to be employed in an electric Kinetic Energy Recovery System for Internal Combustion Engine Vehicles. The system makes use of a supercapacitor as a storage system, and a motorgenerator unit connected to the drive shaft for vehicle acceleration and braking. The system uses available commercial devices, thus obtaining a …

A regenerative braking system for internal combustion engine vehicles using supercapacitors as energy storage elements - Part 2: Simulation results

2020

Abstract In this two-part work, an electric kinetic energy recovery system (e-KERS) for internal combustion engine vehicle (ICEV) is presented and its performance evaluated through numerical simulations. The KERS proposed is based on the use of a supercapacitor as energy storage, interfaced to a brushless machine through a properly designed power converter. In Part 1, the system is described and analysed, and the mathematical model used for the simulations is presented. For each component of the KERS, the real efficiency and the power or energy limitations are adequately considered. In Part 2, the energetic and economic advantages attainable by the proposed KERS are evaluated using MATLAB S…

Biogas composition and upgrading to biomethane

2009

Saija Rasin tutkimus osoittaa, että jätteistä tai energiakasveista tuotettua biokaasua voidaan hyödyntää sähkön ja lämmön tuotantoon. Biokaasua voidaan käyttää jalostettuna myös korkealaatuista polttoainetta vaativissa kohteissa, kuten ajoneuvoissa ja polttokennoissa. Fossiilisten polttoaineiden korvaaminen uusiutuvilla polttoaineilla, esimerkiksi biokaasulla, vähentää merkittävästi kasvihuone- ja muita haitallisia päästöjä. Biokaasun pääkomponentit ovat metaani ja hiilidioksidi, ja lisäksi se voi sisältää pieniä pitoisuuksia energiakäyttöä haittaavia yhdisteitä, joiden määrä ja laatu vaihtelevat. Nämä yhdisteet voivat esimerkiksi estää koko teknologian käytön tai lyhentää laitteistojen huo…
