Abstract
A redundant power supply connected to a common load is provided. Each power supply is connected to the common load through a series of MOSFET pairs. Each MOSFET in a MOSFET pair is individually controlled to reduce power consumption as well as the need for heat sinks on discrete diodes. Moreover, by providing individually controllable MOSFETs the present invention is capable of switching between power supplies without shorting the power supplies or having a significant drop in bus voltage.
