The circuit looks the same because the pure sine wave models actually switch the power on and off at varying levels very fast, about 20khz, so that the output resembles a pure sine wave. This then goes through the transformer that completely smooths out all the switching pulses so that you get a sine wave.  All HF inverters work like this too.
