Abstract
A system comprises a first electrical device, a second electrical device, and a circuit configured to provide power to the first and second electrical devices. The circuit is configured to provide a first voltage across the first electrical device, a polarity of the first voltage being reversible. The circuit is also configured to use the first voltage to provide a second voltage across the second electrical device. A polarity of the second voltage across the second electrical device remains constant when a polarity of the first voltage across the first electrical device is reversed.
