Patent ID: 7102331

Claim:
A generator system having at least first and second modes, the generator system producing a first alternating current output voltage when in the first mode and producing the first alternating current output voltage and a second alternating current output voltage when in the second mode, the second output voltage being twice the first output voltage, comprising: first and second voltage sources each having an output at which they produce the first output voltage; and a switch coupling the outputs of the first and second voltage sources in parallel when the switch is in a first position and in series when the switch is in a second position, the first output voltage produced at the outputs of the first and second voltage sources when the switch is in the first position and the second output voltage produced across the series coupled outputs of the first and second voltage sources when the switch is in the second position with the first output voltage also produced at the outputs of the first and second voltage sources when the switch is in the second position.
