Dynamic switch power converter

A dynamic switch power converter circuit for improving power utilization of a variable direct current (DC) power source whose output varies as a function of time, the dynamic switch power converter circuit comprising

• a controller to detect an input power of the DC power source whose absolute power level varies as a function of time, generating higher voltage or lower voltage based on conditions of an environment in which the DC power source is located, the controller to generate a control signal based on the detected input power, and the controller to receive feedback from the DC power source, the controller to further include a memory to store precomputed power curves for the DC power source;
• and
• a variable input DC to DC converter to operate at one of multiple input voltages corresponding to the detected input power responsive to the controls signal,
• wherein the DC to DC converter includes a plurality of input switches, each configured for a different source input power, where the DC to DC converter selectively activates the switches based on the input DC voltage to most closely match the input power from the DC power source;
• wherein the controller to adjust the DC to DC converter input voltage with the control signal based on the feedback received from the DC power source to more closely match the detected maximum power output of the DC power source based on selective activation of the switches, wherein the controller is to adjust the DC to DC converter input voltage based on the power curves.
