A power converter (14) can include a switching system (18) to convert a direct current (DC) input voltage to an output voltage based on a switching signal having a duty-cycle. A controller (16) can set the duty-cycle of the switching signal, depending on the DC input voltage, to one of a substantially constant value, such that the output voltage follows the DC input voltage in a normal mode, and a value that varies inversely with respect to the DC input voltage, such that the output voltage is substantially constant in another mode.

The present disclosure shows a reconfigurable Dickson Star SC regulator that can support multiple conversion ratios by reconfiguring between various modes. The reconfigurable Dickson Star SC regulator is designed to reduce the number of redundant capacitors by reusing capacitors and switches across multiple modes of operation (across multiple conversion ratios). The present disclosure also shows a hybrid (e.g., two-stage) voltage regulator.

A voltage regulator power reporting offset system includes a monitored power reporting subsystem that determines a monitored power level, offsets the monitored power level using voltage regulator operation offset information to provide a first offset monitored power level, and reports the first offset monitored power level to voltage regulator operation components. A processor power reporting component receives the report of the first offset monitored power level from the monitored power reporting subsystem. A processor power reporting offset subsystem receives the report of the first offset monitored power level from the processor power reporting component, offsets the first offset monitored power level using the processor operation offset information to provide a second offset monitored power level that is different than the first offset monitored power level, and reports the second offset monitored power level to a processing system.

A remotely controlled electronic general switch in DC power electrical supply system(s), ensuring switching and control of current and supply voltage, has an electronic module. The module has a controller or processor connected (i) to the switching and measurement circuit, the controller and measurement circuit optionally being linked bidirectionally, the controller being configured such that, when it receives a voltage and current measurement of the measurement circuit, it is respectively able to verify whether the input voltage lies in a predetermined interval and to instruct current interruption by the switching circuit for a certain duration, as a function of the measured current value, and (ii) to the communication interface, the communication interface connected to the communication bus and controller optionally being linked bidirectionally, such that the controller can be programmed remotely. An addressing bus, connected to the controller, enables selection, from several systems, a particular supply system linked to the general switch.

A configurable impedance circuit is provided, including a filter for filtering a received DC voltage and a controller. The filter includes a first capacitor, a second capacitor, and a selectable switch coupled in series with the second capacitor and coupled to receive a control signal. The selectable switch and the second capacitor are selectively coupled in parallel with the first capacitor. The controller is connected to sense a differential voltage across the second capacitor and configured to generate the control signal to open or close the selectable switch based on the differential voltage across the second capacitor, so as to maintain a voltage range across the second capacitor. According to disclosure of the present invention, the total physical size of the capacitors is reduced and the size of the power supply is reduced accordingly.
