MOSFETs connected in series forming an H-bridge circuit for switching
What you are looking for, I believe, is referred to as a "Half Bridge". The circuit looks like this:



This setup is often found in solid state power supplies and Tesla coils. Looking at the symbols, you can see that it uses two N-channel enhancement-mode MOSFETs and two capacitors. When Q1 is on, current flows from Vcc through Q1, through the load, through C1, to ground. When Q2 is on, C1 is discharged through the load (causing current to flow in the opposite direction). 

Hope this helps.

EDIT: I should have mentioned before that this circuit requires a MOSFET gate driver and a gate drive isolation transformer. I would recommend either a UCC27425 (4-Amp dual, one inverting and one non-inverting) or a combination of the TC4420 (non-inverting) and the TC4429 (inverting) drivers. Obviously you will need to tailor this to the amount of current your load will draw. Connect the driver to a gate drive transformer with two secondaries wound for opposite phases, and connect the secondaries to the FETs. I have edited the above image to reflect this change. There are higher-power versions of these chips that you may want to look into.
