Certainly. You take a 240 to 24 volt transformer, and wire the primary and secondary windings in series by connecting one end of the primary winding to one end of the secondary winding. Now, you have what's known as an autotransformer. Next, you connect your 208 volt input to the opposite end of the primary winding, and the common ends of the primary and secondary windings. Finally, you connect your output to the same end of the primary that you connected your input to, plus far end of the secondary winding, and you'll get 230 volts out. It's important that you connect the windings so that they're in phase. By that, I mean you don't want the windings in the primary to be connected to the windings in the secondary in such a way that one coil is wound clockwise, and the other is wound counterclockwise. Acme transformer has some excellent information on this, as well as the correct wiring diagrams for each of their transformers. Here's the link:
