They don't have converters, they were set up to charge the trailer battery through the tow vehicle's charge line.
You can install a new converter somewhere near the battery location, and connect it to the battery. Just look around for a 120 volt outlet near where you want to locate the converter, so you're not running 120 volt and 12 volt
wiring. The converter will come with a 3 prong plug for 120, and the trailer probably has the old 2 prong outlets, so you'd either have to modify the plug or swap out the outlet. You can connect the ground and neutral wires, since they end up in the same place, though obviously it's better to have separate ground wires.
I'd use a 30 amp converter, with a 30 amp self-resetting breaker in the line to the battery.
