Support design of MPPT solar converter

What systems similar to this have you designed already? Hi I worked on Solar street light using PV with MPPT. Interleaved buck converter used in this topology. I also worked on grid connected solar systems. MPPT algorithm used in incremental conductance method. Proposal: 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, 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.

What systems similar to this have you designed already? Hi, I have design Solar MPPT Boost converter using STM32F407 microcontroller for 300W PV. I have taken Iac and Voc on computer using serial communication and plot the PV curve in MATLAB. I have used IGBT(25N120), Gate Driver (TLP250) and Isolated current-voltage sensing. Proposal: I am an electrical engineer having an experience of four years in power electronics and embedded industries. I have designed and developed Inverters, UPS, Converters, HVDC, PFC Boost and STATCOM. I would like to inform you that i have used Intelligent Power Module upto 5 KW and i could achieved current THD less than 4% in single phase PFC. From simulation side i am very much familiar with MATLAB and PSIM. I have done programming on STM32, Arduino and Raspberry Pi microcontrollers. Do let me know if you have any queries/questions. Let us at least get into the interview stage and discuss things. Hoping to hear from you, Jaydip Kathiry

hi, I can help you. I have worked on mppt solar inverter to drive a 3 phase induction motor. its was designed to work from 300 to 850 vdc. Frequency of the sine wave was adjusted according to the available power.I need the answers of following questions. 1) what is maximum voltage. 2) what is maximum power.

A proposal has not yet been provided

What systems similar to this have you designed already? Good day! Normally I have made converters for car accumulators (batteries). But please keep on reading and you might find the details interesting. Proposal: However I see that you are not a technical person. There are a few problems with the terms and other things. By 5.5Asc you probably mean 5.5 Ampers of current? The panels must not be in series, because the current will be very high and they might burn. The convertor does not have big losses. Parallel gives more power and endurance, if a panel has a maximum current of 1A, that means that through all panels in series, the current must be a maximum of 1A (all of them will produce together 1A), if you put more panels you will raise the voltage, but the current will stay the same. If you want everything to work all the time, a battery will be needed. The normal approach is to put a battery for less voltage and charge it with high current. After the battery we put the convertor, so everything works even if there is no power. For this we can use a car accumulator (battery) also. If I get the the maximum output voltage and current of 1 panel, I can tell you what kind of a battery you will need. I will also need the nominal input current and voltage of the pump (written on the label of the pump normally). There isnt much of a need to control the charging current with a microcontroller. It is good to regulate the charge of the battery, by disconecting it when its fully charged and control the current when its undercharged, which is a simple schematic. The best way would be, charge and work during the day and only work during the night. If you are interested I can offer a device.
