Asking for resources on power electronics. Inverters and chargers

[Albert Luna]

Hi, I am actually working at a inverters workshop assembling and troubleshooting inverters, I study at a technical school here in my country and I want to get more into the world of power electronics on that specific area, contents can have mathematical analysis, something like electronic principles of Malvino kind of book.

I would really appreciate it 

That inverter is not my design or anything I assemble them and troubleshoot them in a man's workshop
