Patent number: 9525286Abstract: A method and system is provided for achieving power shut down or disconnect at individual solar panel level for a DC solar power system. The system provides fail safe power disconnect for emergencies or electrical system maintenance. A high-frequency current source signal is transmitted over DC power lines to each junction box of a photovoltaic panel array. The high frequency signal is transmitted concurrently with the DC power, and is isolated from an inverter by an inductor. A communications receiver circuit controls the PV panel to short circuit the PV panel output terminals and disconnect the PV panel from the output terminals in response to the high-frequency signal.Type: GrantFiled: December 20, 2013Date of Patent: December 20, 2016Assignee: TYCO ELECTRONICS CORPORATIONInventor: Raymond Howard Kohler

Patent number: 9201104Abstract: The power sensing device includes a power input interface in electrical communication with a current sensing circuit and a voltage sensing circuit. The current sensing circuit is connected to a load. The voltage sensing circuit is connected in parallel with the load. A metering integrated circuit and a micro-controller unit (MCU) are included. The metering integrated circuit receives a first analog signal indicating a load current value from the current sensing circuit, and a second analog signal indicating a load voltage value from the voltage sensing circuit. The metering integrated circuit converts first and second analog input signals to first and second digital signals, respectively, and generates the first and second digital signals as digital communication pulses to the MCU. A decoder circuit includes a communications port to send and receive data associated with a sensed current parameter and a sensed voltage parameter.Type: GrantFiled: October 8, 2012Date of Patent: December 1, 2015Assignee: TYCO ELECTRONICS CORPORATIONInventors: Stephen Mark Jackson, Sidharth Dalmia, Mohammad S.

Patent number: 8958216Abstract: A digital isolation circuit includes an encode circuit, a planar magnetic circuit, and a decode circuit. The encode circuit receives an input signal and divides the input signal into a first signal pulse and a second signal pulse. The planar magnetic circuit is coupled to an output of the encode circuit. The planar magnetic circuit includes a primary winding, a secondary winding and a magnetic core. The primary winding is magnetically coupled to the secondary winding through the magnetic core to generate an isolated output signal in response to the pair of signal pulses. The decode circuit receives the isolated output signal from the secondary winding to generate an output signal substantially identical to input signal. A method of digitally isolating a square wave input signal from an output signal using the digital isolation circuit is also disclosed.Type: GrantFiled: October 8, 2012Date of Patent: February 17, 2015Assignee: Tyco Electronics CorporationInventors: Raymond Howard Kohler, Stephen Mark Jackson

Patent number: 8770993Abstract: A connector assembly for installing a device to a ceiling grid, the ceiling grid having conductors provided therein. The connector assembly includes a housing with contact arms mounted in the housing. Contact portions of the contact arms extend from the housing and are placed in electrical engagement with the conductors when the connector assembly is mated with the ceiling grid. Mounting members extend from the housing. Mounting sections of the mounting members are placed in mechanical engagement with the ceiling grid to provide a mechanical connection between the ceiling grid and the connector assembly. A polarity protection/correction member is provided in the housing. The polarity protection/correction member protects the device from failure or damage when the polarity orientation of the device does not match the polarity orientation of the conductors of the grid.Type: GrantFiled: June 1, 2012Date of Patent: July 8, 2014Assignee: Tyco Electronics CorporationInventors: Charles R.
