  • Patent number: 10277032
    Abstract: The present invention discloses a fiducial node DC voltage based DC voltage droop control method with dead-band for HVDC grids. Two levels of DC voltage control e.g. primary and secondary DC voltage regulation are introduced to realize load sharing and DC voltage control in HVDC grids. In the process of primary DC voltage regulation, the power flow regulation ability of the entire HVDC grids can be significantly improved, and the DC voltage and stability of the HVDC grids will be quickly controlled and guaranteed for the benefit of droop characteristic. Secondary DC voltage regulation is achieved by by introducing the load-DC voltage controller. In the process of secondary DC voltage regulation, the burden of accommodating power imbalance by the DC voltage fiducial node will be alleviated, thus improving the ability to resist disturbances of the entire HVDC grids.

  • Patent number: 9565024
    Abstract: A controller provides amplitude modulated power line coding of an output voltage waveform. A transformer has a first winding connected in series with the output. An input mains voltage supply and/or the output voltage are monitored, and the second winding of the transformer is configured in dependence on the monitored mains voltage supply, the monitored output voltage and a target output voltage. This target comprises a voltage which encodes a binary bit of digital information. This provides a feedback approach which enables the transformer to be used to provide an accurate modulation of the binary bit to be encoded.

  • Patent number: 9553448
    Abstract: A system is described that turns off a high power, power supply when a device no longer needs high power. A low power, power supply or a rechargeable battery provides power to determine when the device again needs high power. The low power supply consumes a minimum possible power when the device does not need high power and the power rechargeable battery is not charged. That is, the high power and low power, power supplies are turned on or off based on the real time power consumption need of the device and the charged state of the battery. The power need of the device is monitored by a current shunt monitoring circuit and a control signal monitoring circuit.

  • Patent number: 9543821
    Abstract: A Safe Operating Area (SOA) adaptive gate driver for a switch mode power converter is disclosed. In response to a detection of a fault condition, the SOA adaptive gate driver may limit the peak current in a power transistor (e.g., power MOSFET) of the power converter by limiting the voltage applied to the gate of the power MOSFET or by limiting the current injected into the gate of the power MOSFET. The limited gate voltage or current may increase the margin between an SOA border and the turn-off locus of the drain voltage and current (VD and ID) to ensure safe operation of the switch mode power converter during the fault condition.

  • Patent number: 9520712
    Abstract: A method and a system for controlling the switching time of a device that includes a magnetic circuit and a conductive winding. The method includes acquiring a measurement of the magnetic field generated by the residual flux, by a sensor placed near the magnetic circuit; processing the acquired measurements to infer the residual flux in the magnetic circuit; determining, on the basis of the residual flux, the optimal time for switching on the device. The method also includes switching on a three-phase transformer. The transformer includes a primary conductive winding and a secondary conductive winding surrounded by an enclosure. A magnetic field sensor is on the magnetic circuit and/or on one outer surface of the enclosure.

  • Patent number: 9521730
    Abstract: A circuit (200, 300, 400, 600, 700, 800) interfacing a device (20, 30, 40, 60, 80) with a line-pair includes: a diode bridge (210) having polarity-independent input terminals coupled to the line-pair; a galvanic isolation device (230, 330) receiving a transmit signal and coupling the transmit signal to its output; a variable edge delay circuit (270, 370, 572, 574, 576) that delays rising/falling edges of the transmit signal more than falling/rising edges of the transmit signal; a voltage-controlled variable resistance element (260, 360, 460) connected across output terminals of the diode bridge; and a filter connected to a control terminal of the voltage-controlled variable resistance element. The filter includes decoupled charge and discharge paths to decouple the rise time of the transmit signal from the fall time of the transmit signal. The voltage-controlled variable resistance element couples the transmit signal to the line-pair via the diode bridge.

  • Patent number: 9468026
    Abstract: Embodiments of the invention are directed to control devices configured for use with computing devices. More specifically, the present invention relates to methods and devices for shortening wireless reconnection time by determining the presence of an object or body near a device. When the control device detects an object or body in proximity to the device, the control device may automatically establish a wireless connection with a host devices, such that when the control device receives any user interactions, the wireless connection has already been established, preventing loss of data.

  • Patent number: 9459596
    Abstract: A method for controllably disconnecting a utility power service from a load includes a step of receiving a disconnect command at a control circuit within a utility meter housing. Then, responsive to receiving the disconnect command, using the control circuit to provide a first signal to a first switch operably connecting a charging circuit to an energy storage device.
