POWER MANAGEMENT SCHEMES FOR SURGICAL SYSTEMS

A surgical robotic system includes a robotic arm having at least one surgical instrument and a control device coupled to the robotic arm and configured to control the robotic arm, the control device including one or more components. The surgical robotic system also includes a power supply having: a tower power supply chassis configured to supply first direct current to the robotic arm; a power distribution unit configured to supply second direct current to the one or more components; a first uninterruptable power supply device coupled to the tower power supply chassis and configured to receive a first alternating current from a first alternating current input; and a second uninterruptable power supply device coupled to the power distribution unit and configured to receive a second alternating current from a second alternating current input.
