Your MOSFET must be set-up properly and the drive to your MOSFET must have a higher voltage.

Your capacitor and inductor are too tiny for the load. There's no feedback to regulate the output voltage. It's going to keep rising. It's going over 400V!

And that zener diode is NOT a good idea

Ok here's what I've done. I've increased the inductor and capacitor values. I've replaced the zener with a regular diode. I've reconfigured the MOSFET and I've altered the drive to it. http://everycircuit.com/circuit/5648609056653312

what you guys actually looking for? Some voltages above 120V? Right you know you have already 170V or where do you get your 120VDC from, i have no idea.

I just ignored the wierd voltages and made a few changes. I too am confused about the voltage levels.

Maybe he gets his 120vdc after rectifying the output of an autotransformer? Idk
