Patent ID: 7323829

Claim:
A system comprising: a first pin, a second pin, a third pin, a fourth pin and a fifth pin, wherein the first pin and the fifth pin are operationally coupled to a power source, the second pin and the fourth pin are operationally connected to a load and the third pin is operationally connected to ground; a controller, coupled to the first pin, the second pin, the third pin, the fourth pin, and the fifth pin, that is effective to: drive the load with a first potential in a first phase, wherein in the first phase current passes through the first pin and the third pin; rest in a second phase; and drive the load with a second potential in a third phase, wherein the current passes through the fifth pin and third pin; wherein the controller is effective to convert direct current from the power source into alternating current that is applied to the load through the second pin and the fourth pin.
