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 high frequency transformers 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.

Do You want Line interactive? Trapezoidal output with transformer? Battery charging through same output transformer?

Hi i am experienced embedded engineer and have worked on 150VA UPS before , I have placed my bid on the higher side because i know what will be the development cost of the UPS since i have worked on it before

Hi Sir/Madam, First, I would like to assist you for your work and would like to offer you my services. It takes time and be real Secondly, I am experienced engineer with vast variety of knowledge as I've done lots of projects in my graduation and later on. Expert quality work will be provided in optimum time. Looking forward for your work and hope that you will trust me this time Thanks

Hello, I have many years design experience in various applications. I have designed embedded analyzers, conveyor controllers, autodialers and others. I can handle high-speed communications (CameraLink, USB3, USB2, BLVDS), high-precision anlog (18bit ~ 24bit), high voltage (>1500VDC), high-power (>300W), galvanically isolated designs, IP65, harsh environments, distributed controls and others. I have a lot of experience bringing designs from the conceptual to R&D to prototype to production, including installation at customer site and A/S. I have implemented low-power, high-efficiency systems for USB applications and others with both FPGA and MCU solutions. Miniature size DC/DC converters, Power banks, USB isolators and high-density designs as well, and I can provide design support and firmware for many MCU's and Xilinx FPGAs, and also GUI/programming for Windows environments. I can provide (extra cost) finished PCBs assembled and tested (for non-special requirements), panelized layouts ready for SMD assembly, and extra documentation for CE certifications and the like. I use Eagle 6.5 for schematic and layouts, LTSpice for simulation. I can also provide designs for enclosures or mechanical parts using AutoCAD (3D in MDT). Let me know if I can be of assistance. Best regards, Stuart Borden.
