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

A Bi-fold door will fold inwards on the sidewalls of the door and hence space requirement for opening will be less.This is highly suitable for Home Elevators and Buses. A 24V PMDC (Permanent Magnet DC Motor) with a built-in Encoder will be used to operate the Door Operator of the Bifold door. The controller should have 3 Speed Control and should follow the Ideal Speed Control curve (shown below) to at least 85%. It should have a soft start to avoid jerks during start of the opening and closing. The speed at the full opening and full closing should be very low so that the people can enter or exit unheard. While closing if someone extends hand on the door line, the door should immediately start opening and again close after a pre-set time. All the 3 Speeds in Opening and Closing should pre-adjustable independently.

Arduino based phase angle controlled Zone Heater What’s great about this design? The circuit developed from scratch and is not copied from any source. We have developed this circuit with latest technology and so it’s not followed the standard track. Micro-processors are not very good for trouble-free operation if the product is solely dependent on software. In this particular application the board has to handle 3 phase AC as well as DC and Signal Voltages and so the design has to take care of the inter-tack noises. The noise elimination is important or otherwise the system will definitely malfunction. It’s difficult to make people understand the importance of hardware in this age of software. Industrial equipment design is now dependent on more and more use of hardware as this has the ability to tackle inter-track noises and supply generated low frequency noises. It’s quite easy to eliminate high frequency noises by EMI / RFI Filters, but low frequency noises (60 Hz) is hard to e

Engineers Akademy developed a Prototype of a Fully Automatic Motion Controller to move a table in Bernouli’s Spiral movement. The Prototype was developed from scratch. Autonics - 2 Axis high speed programmable motion controller – Model: PMC-2HS was used to develop “Bernouli Spiral” motion through a Stepper Motor controlled X-Y Table. A Digital I/O Circuit was developed to feed motion control data to the Motion Controller. A double sided PTH PCB was designed and made for the Digital I/O and allied circuits. Inductive proximity Sensors were used to locate the “Home” position and “End” positions of the X-Y Table. The Sensor Actuator circuit activated a Ardunio UNO card to send digital signal to the motion controller. The motion controller was pre-programmed to have 4 type of ‘Bernouli Spiral” movement which were selectable by rotary switch. The machine was fully automatic.

A Bi-fold door will fold inwards on the sidewalls of the door and hence space requirement for opening will be less.This is highly suitable for Home Elevators and Buses. A 24V PMDC (Permanent Magnet DC Motor) with a built-in Encoder will be used to operate the Door Operator of the Bifold door. The controller should have 3 Speed Control and should follow the Ideal Speed Control curve (shown below) to at least 85%. It should have a soft start to avoid jerks during start of the opening and closing. The speed at the full opening and full closing should be very low so that the people can enter or exit unheard. While closing if someone extends hand on the door line, the door should immediately start opening and again close after a pre-set time. All the 3 Speeds in Opening and Closing should pre-adjustable independently.

We have developed this circuit with latest technology and so it’s not followed the standard track. Micro-processors are not very good for trouble-free operation if the product is solely dependent on software. In this particular application the board has to handle 3 phase AC as well as DC and Signal Voltages and so the design has to take care of the inter-tack noises. The noise elimination is important or otherwise the system will definitely malfunction. It’s difficult to make people understand the importance of hardware in this age of software. Industrial equipment design is now dependent on more and more use of hardware as this has the ability to tackle inter-track noises and supply generated low frequency noises. It’s quite easy to eliminate high frequency noises by EMI / RFI Filters, but low frequency noises (60 Hz) is hard to e

Engineers Akademy developed a Prototype of a Fully Automatic Motion Controller to move a table in Bernouli’s Spiral movement. The Prototype was developed from scratch. Autonics - 2 Axis high speed programmable motion controller – Model: PMC-2HS was used to develop “Bernouli Spiral” motion through a Stepper Motor controlled X-Y Table. A Digital I/O Circuit was developed to feed motion control data to the Motion Controller. A double sided PTH PCB was designed and made for the Digital I/O and allied circuits. Inductive proximity Sensors were used to locate the “Home” position and “End” positions of the X-Y Table. The Sensor Actuator circuit activated a Ardunio UNO card to send digital signal to the motion controller. The motion controller was pre-programmed to have 4 type of ‘Bernouli Spiral” movement which were selectable by rotary switch. The machine was fully automatic.

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
