Pick and design a schematic for inverter buck-boost controller

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, Regulated power supplies design with universal input to DC output, 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 work experience to design from few watts to KW range meeting all compliances like EMI/EMC and safety standards UL etc.

I have over 35 years experience as an electronic design engineer, please see my profile for more details The current price and timescales are only place holders to allow me to communicate with you If you think I can help then please send me further details such as what current you need at 50 volts? Best Regards Dave Lelievre

I am an Electrical Engineer having specialization in Electronics and Control, teaching in Electrical Department at FAST National University Pakistan. I am also persuing my MS degree in Electrical Engineering with specialization in CONTROL. I have taught the followings courses, and also done many projects related to these subjects as well as related to consumer electronics products. 1. Control System Design & Modelling (Continuous, Discrete, Linear, Non-Linear, Optimal, Fuzzy Logic + Matlab & Simulink) 2. Digital System/Logic Design (Verilog, VHDL, Logisim) 3. Micro-controllers (8051, Arduino, PIC) 4. Power Electronics (PSIM, MATLAB, PSpice) 5. Control of Electric Machine Drives 6. Circuit Analysis and Designe etc 7. PCB Design (Proteous + Ultiboard + Altium Designer) I assure you, if you assign your project to me, you surely gonna work with me in future. Note: I also provide the solution of mechanical engineering related projects.

Greetings, I have good expertise with DC-DC converters of different topology. Please see my portfolio/profile for details. This project can be done by boost+inverting boost or boost+negative boost topology. However the important aspect is your current rating. That will determine quite a few things so need to know that. Assuming other specifications are not that stringent, I can give you the design < 2days and can explain you its working as well. More importantly since you will build it at your end and might need some debug support - I am open to offer that as well. Look forward to hear from you. T & R Alok Pugalia

Designing switchers for two decades upto 10KW and are now used in Railways and Defense. Will need some other parameters like ripple, min/max load current ,isolation.

A proposal has not yet been provided

i am perfect for your task i have done that already for my college project in my final year

Like you i am also good at electronics but never worked with switches. but, friend of mine have very good knowledge and practice in power electronic. With his help, we both can learn to do it.

i have worked on a similar problem in my course of power electronics where we imployed the buck bost converter in a project i am sure if i work on it for some time i can provide you with the schematcic using multisum or protius

I am an electronics engineer. Have developed top class power supply designs for OEMs in USA and UK.

Hi dear, I am Electrical Engineer Working as design engineer in SMPS industry, I already Design many Flyback and boost-buck converters as it is cheapest solution. This bid include Schematic, Gerber File, Components list. Thanks VIVEK

hi sir, you need DC source of 50V and -50V but I need to know the rated current for your loads, Also, Boost converter is a switched mode power supply that switching frequency effect in the ripple of output voltage, So we need to know the nature of your load (resistive,Inductive, or capacitive load ) I'm an electrical engineer that have more knowledge and experience in electronics design, So I hope to trust me and start to discuss in project to perform it in the fastest time and in the best quality. best regards, thanks.
