The PDU further includes a microprocessor coupled to the ADC and configured to measure a scale of a signal output from a first channel of the ADC, compare the scale of the signal to a sensitivity threshold, and select, for a first outlet corresponding to the first channel, a reference voltage of a plurality of reference voltages for input to the ADC based on a result of comparing. Various embodiments allow using an ADC to measure low level outlet currents of less than around 300 mA in addition to high level currents such as around 20A. | 05-19-2016 |
20160149412 | VOLTAGE MONITORING CONTROL DEVICE AND VOLTAGE CONTROL DEVICE - A voltage monitoring control device includes: a transceiver unit communicating with local voltage control devices adjusting a control amount of voltage control apparatuses that control a voltage on a power distribution line in a high-voltage system every second cycle based on a command value updated every first cycle; an indicatable-range updating unit determining an indicatable range, which is a range of reactive power indicatable to the local voltage control device, based on a control result received via the transceiver unit from the local voltage control device that controls a reactive-power-modified voltage control apparatus, the control result being a limit-value time or a limit-value-time ratio; and a reactive-power determination unit determining a reactive-power command value, which is a command value updated every first cycle based on the indicatable range and transmitted, via the transceiver unit, to the local voltage control device that controls the reactive-power-modified voltage control apparatus. | 05-26-2016 |

20160161531 | MAGNETO-RESISTIVE SENSOR DEVICE AND MAGNETIC BIAS REGULATOR CIRCUIT, ALONG WITH SYSTEMS AND METHODS INCORPORATING SAME - Various embodiments of the present disclosure are related to systems, devices, and methods for current sensing. In one example, a current sensing circuit includes a magneto-resistive sensor device proximate to a current carrying conductor and configured to output a voltage representative of a current carried by the proximate current carrying conductor and a first sensor feedback loop responsive to an alternating magnetic field generated by the current carried by the current carrying conductor. The first sensor feedback loop is configured to supply a bias current to the magneto-resistive sensor device and substantially cancel the alternating magnetic field generated by the current carried by the current carrying conductor. | 06-09-2016 |
20160164283 | POWER MANAGEMENT CIRCUIT AND MOBILE TERMINAL - The present disclosure relates to a power management circuit and a mobile terminal having a first switch for blocking current. The first switch blocks an input of an external power supply in a case that a predetermined load operates in a large current/voltage mode. A bi-directional DC converter boosts a battery voltage and supplies it to the load. Thus, the circuit is simplified and the number of components is reduced for power management. | 06-09-2016 |
20160164288 | LOAD POWER DEVICE, SYSTEM AND METHOD OF LOAD CONTROL AND MANAGEMENT EMPLOYING LOAD IDENTIFICATION - A load power device includes a power input, at least one power output for at least one load, a plurality of sensors structured to sense voltage and current at the at least one power output, and a processor. The processor provides: (a) load identification based upon the sensed voltage and current, and (b) load control and management based upon the load identification. | 06-09-2016 |
