4KW SMPS DESIGN AC/DC IN-230V OUT-48VDC

Dear Sir/Mam, I am current working as a hardware design engineer. I Had worked on 12v 120A CCTV power supply adapter. Also archived IEC standards for for the power supply application, I did designs with over voltage and over current protection and design to measure primary voltage at secondary side. By seeing your voltage and power requirements I think it for battery charging application. Based on your power requirement Full bridge or phase shifted full bridge converter will be suitable for the project. Depending upon the BOM cost we can choose between FET or IGBT and the gate driver topology. It is tough to get the trust as new freelancer. I will make sure that you wont regret on your decision giving me this project. If you have any doubts call me +919894564199 or send and email at [login to view URL]@gmail regards Abiraman.S

Hi, I am a post graduate power electronics engineer and having very good industrial experience of 8+ years in R&D and project development. I am excellent welding power supplies design, Plasma ARC power supplies, high frequency transformers design, solar grid tie transformers, electrical vehicles design, circuits design, multi-channel LED Drivers, Regulated power supplies design with universal input to DC output, Audio amplifier, drives design, Filters design for harmonic analysis and Power factor correction, SMPS, LED drivers, DC-DC, AC-DC converters design, PFC interleaved boost converter, Battery management system, Battery chargers, UPS design, sine wave Inverters, solar grid tie inverters, Solar battery chargers and street light systems design from few watts to KW range using Buck, Boost, and Buck –boost, Interleaved boost/buck, Fly back Push Pull and H-bridge inverters. I have very good experience to design high voltage power supplies up to 50KV for capacitor charging power supplies using soft switching topologies. I have work experience to design from few watts to KW range meeting all compliances like EMI/EMC and safety standards UL etc.

Professional engineer with 40 years of experience in design and development Relevant Skills and Experience Offer work at ₹550/hr rate

I have completed Electrical Engineer. Now,I am studying MSc mechatronics Engineering One best university of Pakistan. I am very expert in many software and Programming languages..I have done many projecct on MATLAB, Solid Works,Proteus, PSCAD, ARDUINO, C++. Writing is also my hobby.I have written my own bachelor thesis.I have written many articles for many people during working online. I am also expert in automation system. I have done many industrial project on PLC, Pneumatic System and Relay logics.

I can design the supply in 4 days and can help you out with handling other parameters also , the supply will be dynamic and will be capable enough to handle as much load as you want

Dear Sir: Please specify the kind of load which will be connected to this power supply and if it needs input power factor compensation. Thank you in advance Best wishes Carlos de los Ríos
