Hello, I finally got the 5W resistors and a Zener rated at 2W. Now whilst the zener diode remains cool, the 5W resistor still gets too warm to touch. Is that what i should expect?
I have attached my schematic for comment if you can but I cannot see that I have deviated too far from the published design, I just made it for 5 phases. The design 'works' but I am uncomfortable with the generation of that much heat on something that should (I believe) consume very little current.
I would be grateful for any insight you may be able to provide.
