"We Call This CONCEPT An INFINITY CHARGER; There Is NO LIMIT For VOLTAGE And CURRENT In This Configuration"

You claim that your chargers are like LEGO modules. What’s your unique recipe?
We have 30+ intellectual properties in design but this is The One. The innovation that we have got here is in power electronics. You cannot connect two power generating converters in series, because you would get into load balancing issues. We also faced that problem but we were able to solve it through multiple iterations, and we used a special switching mechanism called GaN FET. We were able to switch GaN FET switches at a frequency of 1MHz, increasing the power density of the charger, which is a great achievement in power electronics systems. With this switching frequency, as well as the hardware we developed, plus the homework we did, we were able to connect the modules in series and parallel to enhance both current and voltage.
Why do you use GaN FET? What’s special about it?
We are using GaN FET because we wanted to make sure that we are switching at a frequency of 1MHz or more. If you use MOSFETs and other FETs available in the market, you can’t switch at that frequency. If you try to do that, it starts burning. Secondly, when we switch at a higher frequency, the overall size of the power electronics grid will come down. So, we wanted to make a compact and highly efficient power electronics converter and that’s why we used GaN FETs.
Was this innovation intentional or accidental?
