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.

Good morning Dear. This project is something serious. I work with these equipments intended to run as induction heating generator, UPS, etc. I can do this, but don't cost 30000 INR... This work I send you the whole information needed to construct it but, additionaly, I need to costruct its prototype to test its behaviour so, I can send you the tested prototype. I'm electrical engineer, with experience in power electronics, NOT MICROCONTROLLER. I can send you my CV, if you're interested. I await for you evaluate my proposal. Best regards.

We are a power-electronics engineering agency with strong experience designing industrial DC-DC converters and high-power DC-AC inverter systems. We can design a complete, closed-loop solution covering both the 50–90 VDC to 230 VDC boost stage and the 230 VDC to 230 VAC inverter with a 5.5 kW output capacity. Our approach focuses on stable voltage and current regulation using proven control topologies, robust gate-drive and protection circuitry, and layouts suitable for industrial environments. While we prioritize reliability and controllability over peak efficiency—as per your requirement—we ensure safe operation, thermal stability, and clean output under varying load conditions. We have delivered similar power-conversion systems for industrial equipment and can share relevant examples of our prior work upon request. With structured documentation and professional execution, this is well within our expertise, and we’re confident in delivering a production-ready design. Looking forward to discussing technical details and timelines.

What input source characteristics should I design for on the 50–90 VDC bus, including ripple, surge current, short-circuit capability, and allowable inrush? What regulation targets do you need at 230 VDC and 230 VAC, specifically steady-state accuracy, transient response, output ripple on the DC link, and THD on the AC output? What load profile will the 5.5 kW inverter see, including peak overload duration, motor or inductive loads, power factor range, and regenerative energy or backfeed scenarios? What protection and compliance requirements are mandatory for your industrial environment, such as isolation level, grounding scheme, required creepage and clearance, OVP OCP OTP, EMI limits, and fault behavior?
