Abstract

In various embodiments, the energy efficient power supply utilizes switching control energy from an onboard energy storage device, or from an external utilization device power, to power the switching function of the power supply to switch between a zero energy use state, and an energized state, providing standby, low-draw, measured-demand, and full-output energy; variable, as the utilization device, or devices, require. Energized switching control is achieved by completing, or providing, the control circuit when the power supply is connected to a utilization device, or devices, or when the power supply is connected to a utilization device, or devices, and a utilization device signals, or when utilization devices signal, that power is needed from the power supply. De-energized switching control is achieved by disconnecting the power supply from a utilization device, or devices, or when a utilization device signals, or when utilization devices signal, that power is no longer needed from the power supply.
