So I just put 39vAC into an old bridge rectifier. I connect bridge rectifier to three 10,000uF capacitors in parallel. As soon as I supply power, I see smoke. I disconnect capacitors, capacitors appear to be fine. But rectifier is spewing out smoke, not sure why. It is rated for 400v and 25amps. It is probably 18 years old though. The transfer was making odd sounds while the rectifier was smoking; almost like a stalling motor. THis is what made me unplug the power. So, what will happen if I leave it plugged in?
