put the resistor on the ac side of the rectifier and use cheap ac SSR's
i built a SSR voltage clamp that triggers at around 220vac, sends current through a 10ohm 240v furnace heating element.
i placed a full wave rectifier on the 208 volts line to neutral from a 240vac rotary phase converter, followed by a 150 ohm resistor and a string of ~300 volts dc worth of 1 watt 24v zener diodes, directly into a SSR (which is protected with its own zener, and a 10uf capacitor keeps the SSR on for just one line cycle and not one more)
when my friend's milling machine sends 70 amps back up the line during spindle stop, the 208 volts from the rpc increases to 250 volts and there is at least 25 amps rms flowing through the resistor, a little in excess of the 25amp SSR i bought. without the circuit the spindle drive will shut off due to overvoltage.
it has held up for thousands of cycles for a year now.
my first attempt burned up, used half watt zeners and a 68 ohm resistor. zeners got warm and failed shorted
