Abstract

An electrical system can include a power supply coupled to an electrical load, where the power supply includes an AC/DC converter and a number of DC/DC converters, where the AC/DC converter provides raw DC power to the DC/DC converters, where the DC/DC converters receive the raw DC power and generate final DC power for the electrical load. The electrical system can also include a controller coupled to the power supply, where the controller selectively enables and disables the DC/DC converters.
