Hi to everybody!
I am trying to repair power invertor Whitenergy AC/DC from 24V to 230V 2000W. On the PCB I have found that there are two parts burned out. On the PCB there is a resistor marking R59, R60. But only leads are sticking out on the PCB and it can not be seen what parts used to be there.
I guess these parts might be resistors with some small value (less then 1ohm). But I am not sure. They are in series with the load (230V socket) in the H-Bridge circuit.
I have searched on the internet for the possible part which can be there. It seams that there can be also some filters or inductors. But I am not sure.
Does anyone have an idea what is the best to put there? Attached are some pictures to describe the problem.
Thanks Martin
