Patent ID: 8760895

Claim:
Apparatus for generating AC power, comprising: a DC/AC inversion stage capable of generating at least two of a single-phase output power, a two-phase output power, and a three-phase output power; and a conversion control module, coupled to the DC/AC inversion stage, for driving the DC/AC inversion stage to selectively generate a number of phases of output power from the at least two of the single-phase output power, the two-phase output power, and the three-phase output power based on an input power to the DC/AC inversion stage, wherein the conversion control module (i) drives the DC/AC inversion stage to generate the single-phase output power when the input power is less than a first threshold, (ii) drives the DC/AC inversion stage to generate the two-phase output power when the input power is between the first threshold and a second threshold, and (iii) drives the DC/AC inversion stage to generate the three-phase output power when the input power exceeds the second threshold, and wherein the conversion control module drives the DC/AC inversion stage to operate in burst mode when the input power satisfies a burst mode threshold.
