Good morning, my name is Eriksong Peñaloza, I am a mechatronic engineer, with experience in various topics of engineering
I have developed projects in electronics, using tools such as PIC microcontrollers, Arduino among others.
I can develop your project in a good way, I just need to know if the controller will be submerged in water and will be part of the source or will be the source in its entirety submerged in water ...
I think it could be developed using a microcontroller to take the commands of the buttons to increase and decrease the value of the voltage, as well as to generate the required polarity change of the source, besides that element of control would provide greater reliability in the voltage levels delivered ...
I would be delivering the electrical diagram, the programming code of the microcontroller, the .hex file to load the program into the microcontroller, the PCB diagram for the development of the board and a document with the detailed explanation of the use of the source and the list of materials with their respective component codes ..., I would need to know the use that will be given to the source to know if the design with military grade components.
You can contact me and we expand the information about it.
