Claim Text:
1. An apparatus comprising: a plurality of transformers each having a primary winding and a secondary winding where the secondary windings are connected in series; a battery; a plurality of switches, each coupled to one of the plurality of transformers, each switch intermittently closes to complete a circuit between the battery and the primary winding of each transformer; and a processor that individually activates the respective switches of the plurality of transformers in a predetermined order to generate an alternating current voltage across an output of the series connected secondary windings; and a precess processor configured to rotate the predetermined order after every half cycle, such that a first switch activated in a first repeating operational slot during a first half cycle is rotated to activate in a second repeating operational time slot during a second half cycle, and a second switch activated in the second repeating operational slot during the first half cycle is rotated to activate in a third repeating operational time slot during the second half cycle.
