So I'm trying to understand why you would use a cycle time of anything smaller than 8.33ms. Even if you can get the SSR to turn on at a random time (and many SSRs will), it will not turn off until it hits the zero crossing, which occurs every 8.33ms.
I would think the best way to do this would be to phase control the SSR, by locking to the line frequency so that you can turn the SSR on at a know time relative to the next zero crossing. This would give you the best duty cycle control possible, but you still can't do it faster than using a 8.33ms period (by any method).
