Abstract
A system for controlling a plurality of power converters in a power system so as to turn each of the plurality of power converters into an ON state or an OFF state as a function of a sensed input power and a sensed output power such that one or more of the plurality of power converters in the ON state are operating in an optimal power efficiency range.
Claims24
A system for controlling a plurality of power converters in a power system for supplying power to a load, comprising
- a plurality of switched capacitor type power converters forming an array for converting power between a first power level and a second power level when operating, wherein the plurality of switched capacitor type power converters are arranged in parallel relative to each other and wherein each of the switched capacitor type power converters has a plurality of capacitors for storing power,
- a common input power line directly coupled to an input of each of the plurality of switched capacitor type power converters on an input side for providing input power at the first power level,
- a common output power line directly coupled to an output of each of the plurality of switched capacitor type power converters on an output side for providing output power to the load at the second power level,
- a controller directly coupled to the outputs of the plurality of switched capacitor type power converters for controlling a power output of the plurality of switched capacitor type power converters,
- an input sensing circuit coupled to the common input power line and to the controller for sensing the input power on the common input power line and transmitting an input power signal to the controller, and
- an output sensing circuit coupled to the common output power line and to the controller for sensing the output power on the common output power line and transmitting an output power signal to the controller,
- wherein the controller is configured to control each of the plurality of switched capacitor type power converters so as to selectively turn one or more of the plurality of switched capacitor type power converters between
- an ON state at a first clock frequency so as to supply power to the load and
- an OFF state at a second lower clock frequency where the power converter does not transmit power to the load and remains operative so as to charge the plurality of capacitors associated therewith,
- wherein the plurality of switched capacitor type power converters are controlled as a function of the sensed input power and the sensed output power such that one or more of the plurality of switched capacitor type power converters in the ON state are operating in an optimal power efficiency range.
