I am not sure exactly what you are getting at by using the term alternator. But a good option is any of the honda or yamaha inverter generators. These have a DC generator system running a power inverter so the power output is much more constant. They are also quieter and more fuel efficient because the engine RPM can slow down to match the load where a normal generator must run at 3600rpm to get your 60hz power.
