A power converter delivers electrical power from an electrical power source to a load according to a plurality of operation modes corresponding to different levels of input voltage or output current. The power converter comprises a power stage for delivering the electrical power from the power source to the load, a switch in the power stage that electrically couples or decouples the load to the power source, and a switch controller coupled to the switch for controlling the on-times and off-times of the switch according to the plurality of operation modes. Each of the operation modes correspond to associated ranges of at least one of an input voltage to the power converter and an output current from the power converter, where the associated ranges are different for each of the operation modes.
A power converter comprising:
A controller for controlling a power converter, the power converter including a power stage for transferring electrical power from a power source to a load and a switch in the power stage that electrically couples or decouples the load to or from the power source, wherein the controller is coupled to the switch for controlling on-times and off-times of the switch according to a plurality of operation modes, the operation modes including:
A method of shaping input current to a power converter, the method comprising the steps of:
A power converter comprising:
