24 VAC from 12 VDC power converter for 24 VAC control lines to home HVAC

In a power outage your natural gas furnace won't work because the control valve for the gas is energized by 24 VAC.  A 12 VDC car battery can get this going if you have a converter.  Anyone know of such a switching converter?
