EV Charger Design, Home Automation Products

Subodh Sarkar [login to view URL] (Hons) in Electronics & Electrical Communication Engineering from Indian Institute of Technology, Kharagpur, India. I am best at designing “Electric Vehicle Charger products.” Credit- I have designed a complete range of Smart Public Charging Stations for Electric Vehicle including system engineering for a US Company. Executive Summary - I have enjoyed more than (40) forty gratifying years as a professional engineer in Industries in the US and India in Industrial Automation, Electric Vehicle Chargers, and Home Automation Products. I am now open to assignments in design, prototype development, & test of EVSE and Home Automation products. My published engineering eBooks- I have published some engineering eBooks at Amazon & Smashwords, which enjoys popularity among professional engineers and students. Here are two eBooks relevant to Electric Vehicle. (1) Electric Vehicle Service Equipment - EVSE - Comprehensive Design Inputs of Level 1, 2 & 3 Chargers: Circuits, Design & Infrastructure of EVSE Kindle Edition at Amazon: You can view this eBook on Amazon Kindle. (2) Lithium-Ion Battery - The Power of Electric Vehicles with Basics, Design, Charging technology & Battery Management Systems You can view this eBook on Amazon Kindle. Some of my Important achievements. (1) A Mangood Cop. Group Company) – Chicago, USA. As Design Engineer. Achievement: Design of a Fully Automatic Rail Weigh-In-Motion Weighing System. (2) As Self Employed – EV Charger Design & System Engineering Successful Designs which have been converted to a marketable product: (A) I have developed an indigenously High-Level Communication and Hardware Handshaking Card to exchange charging parameters with EV to Charger for the following three types of Standard Connectors: (a) Type 2 – for 1-phase AC Charging & 3-phase AC Charging (b) CCS-2 (Combo) – High Power DC Charging via dedicated Pins with Combo-2 (c) GB/T (China) – Conventional AC Charging & High Power DC Charging (B) EV charging station power module – This is the most important design made by me for EV Charger development. The Power Module has to be smart and highly efficient for electric vehicle chargers. Whether it’s a PFC stage or the DC/DC power stage design, I have the right circuits to design an efficient power module. It isn’t easy to design Power modules for EV charging stations as it requires high-level expertise to enable: (a) Accurate sensing and control of power output (b) High-power density to support faster and higher power conversions (c) Efficient PFC and DC/DC conversion to reduce losses

Magnetic Levitation and Its Applications to High Speed Or Maglev Trains

http://ezinearticles.com/?Magnetic-Levitation-and-Its-Applications-to-High-Speed-Or-Maglev-Trains&id=5100112
Magnetic Levitation trains are super fast trains. In this Article, we will try to explain the Levitation phenomenon in applications to High Speed Trains. How does a Magnetic Levitation Train work? Instead of running on electricity or diesel, it runs on powerful magnets. Magnets move these trains at high speed. The magnet creates a powerful magnetic field and this field moves the train forward. Instead of riding on the rails, the train is levitated i.e., it rides on a cushion of air. Britain made the first
