Abstract
Described are devices for automatically adapting electrical polarity from a power source to a specified output polarity for use by an electrical load. In one implementation, power adaptation circuitry comprising one or more bridge circuits accept electrical power of unspecified polarity and output specified polarity. The bridge circuit may comprise a plurality of field-effect transistors (FETs) configured such that a particular subset of the FETs are energized to conduct electric current to the outputs when a particular polarity is applied at inputs.
