100/-100V square wave generator from 170AC sourceview story

http://forum.allaboutcircuits.com – Hi all, The goal is to generate a +/- 100V square wave from a 120 VAC wall source. In addition, I need to be able to control the frequency and amplitude from a microcontroller. I'm currently using a half rectifier and capacitor circuit to create the +/- 100V and feeding that into a comparator op-amp and using a signal from my micro to switch the output. (Embedded)
