What frequency are you running the PWM at? I have run the shay and climax with an Airwire and there weren't any problems. I believe that Airwire runs in the 20 to 30KHZ range.

Perhaps your PWM is allowing simultaneous conduction (very short short circuits of the power suppy) instead of shutting off between pulses. Just a thought. You would need an oscilliscope to look at the signals.
