I'm looking for an expert in power electronics to design a conversion system for my industrial equipment. The project consists of two parts: 1. Designing a boost converter that will convert 50 -90 Volt DC to 230 Volts DC 2. Constructing a system to convert 230 VDC to 230 V AC with an output capacity of 5.5 KW The efficiency of the system doesn't need to be top-tier; standard efficiency is acceptable. However, the output voltage and current control must be automatic, utilizing a closed-loop system. Experience with designing similar systems is a plus. Please provide evidence of your previous work in the power electronics field, particularly with boost converters and industrial equipment.

I have a catalogue of electronics ready to launch and I need each item live on , , Pepita, eMAG, and Kaufland. Also on their local versions in Poland.
