PWM is not the answer to everything.
dont be a one-trick pony.
what you probably want is a big-ass SCR (or Triac) and a zero-crossing detector.
you could turn it on for, say, one half-cycle every 4 cycles. adjustable.
and you switch on at the zero crossing, so no spikes.
an SCR will turn itself off on every negative cycle, so it's always under control.
