Today it has become popular to convert rectangular Starlink terminals into a flat “automotive” version. There are tons of projects like this one or this. People cut the terminal case and pack it in a custom flat housing. Typical usage: RV. An essential part of such modifications is the change of the power scheme.
A few years ago, I wrote about the powerful DC motor driver based on IR2110. This construction appeared to be quite popular. This time I want to describe a much compact and simpler (but still very powerful) solution with IRS2104. This device can be used to control any power-hungry DC load like DC motors, heaters, and so on.
This is the second part of the Allsky cycle, and I want to describe powering and protection of this device. Please read the first part to get basic information about this project.
