I am experienced in developing transformerless inverters. My technical approach involves using a high voltage to low voltage step down transformer to reduce the voltage to the desired level. I will then use an inverter to convert the AC input to the desired DC output. Additionally, I will also use power electronics components such as MOSFETs, SCRs, and IGBTs to control the power flow. To ensure the success of the project, I have two deep questions for you: 1. What is the desired output voltage, current, and frequency for the system? 2. What are the safety requirements for the system?

Hi, I understand that you need a step-down (480V to 20V) voltage controller circuit without a transformer. The main thing is if the output is DC or 3-phase AC. We can realize if it would be AC with a 3-phase AC chopper. For DC output we can do it with a buck converter. One of my projects related to this topic is; - Infrared Textile Dryer control unit (control card and power-electronics layer) is a 3-phase chopper. Some of the power electronics projects that I have been involved in; - Design and implementation of a dc-dc power converter for energy management in fuel-cell/ultracapacitor hybrid power train in electric vehicles, funded by Yildiz Technical University, PI (Applicant), Aug. 2014 - Dec. 2016. - Design and implementation of a double input and bi-directional dc-dc power converter for energy management in battery/ultracapacitor hybrid power train in electric vehicles, funded by The Scientific and Technological Research Council of Turkey, PI (Applicant), Sep. 2013- March 2016. Please write me to discuss the power level, load type, and other details. Regards,
