Operation analysis of high efficiency grid connected bi-directional power conversion system for various storage battery systems with bi-directional switch circuit topology
In recent years, there is an increasing demand for various types of storage battery systems, such as home battery systems, V2H(Vehicle-to-Home)/V2G(Vehicle-to-Grid) systems, and UPS systems. Performance requirements for the power conversion system within these storage battery systems are small size, light weight and high efficiency. We propose a new power conversion system so called the GAP-D3 converter that is a bi-directional power control system, comprising of a bi-directional switch circuit topology with natural commutation switching mode. This paper describes the features of GAP-D3 converter including this new current compensation control with simulation and experimental results.
Operation Analysis for Seamless Charge and Discharge Control of High Efficiency Grid-Connected Bi-directional Power Conversion System for Storage Battery Systems with Bi-directional Switch Circuit Topology
In recent years, various storage battery systems, such as home battery system, V2H/V2G system, and UPS system, have spread rapidly all over the world. We propose a new power conversion system for use in the previously-stated storage battery systems. This paper describes operation analysis of this system for bi-directional power conversion with fundamental grid-interconnection. Good output follow-up controllability characteristics of the proposed system are shown through computer simulation results. キーワード:蓄電池システム,系統連系,絶縁型 DC-AC,双方向スイッチ回路,遅れ電流補償,シームレス充放電制御
Complex telemonitoring of patients and elderly people for telemedical and homecare services
The paper presents a project that has as main goal researches, design and implementation of an electronic-informatics-telecom and scalable system, that allows the automatic and complex telemonitoring, everywhere and every time (at home, in hospitals, at work, of mobile subject etc, using several communication paths), in real time, of persons with chronic illnesses, of elderly people, of those having high medical risk and of those with neurolocomotor disabilities.
