No schematic, but here is what I am experiencing:
I built a simple PWM control to replace the battery on a portable saw:
It's rather simple, having a 120v power cord>fuse>switch>large-transformer>diode-bridge>electrolytic-filter-capacitors>pwm circuit>DC power saw.
My former battery-operated circular saw now resides upside-down, doing service in my shop as a mini-table saw. It is plugged into the same circuit as my shop computer tower. Sometimes, I notice that my computer kicks off after using the saw, but the circuit-breaker doesn't trip. At first, I thought I had a bad neutral, as once I lost power completely. I was able to hunt down a fiddly wire nut, and I thought I had found the trouble, but the situation is still occurring. I suspect that I am getting some kind of back emf/emp from my DIY table saw that whacks my computer/power-supply.
Does this seem a worth-while direction to go, or should I look for something else?
