Abstract:
1. A switch-mode power supply, comprising: a power circuit component configured to provide power to a pump that provides fluid from a container to some other device, including an appliance; and a switch mode power supply controller having an electronic switch, including a MOSFET switch, coupled to the power circuit component to turn off the switch-mode power supply, configured to receive signaling containing information about at least one control parameter selected from a group including a pressure at an outlet of the pump, a fluid level in the container and a temperature of a motor of the pump, and also configured to turn off the electronic switch, and shut off the switch-mode power supply and the power provided from the power circuit component to the pump based at least partly on the signaling received, so that the power circuit component substantially does not draw power and heat up when the pump is shut off.
