Abstract: An apparatus comprising a signal transformer coupled to a power line and a signal transmission, reception, or detection circuit. A sensor is configured to be responsive to the power line current or magnetic flux generated in a ferrite core of the signal transformer. When the sensor indicates that the flux generated by the power line current mat cause an attenuation of the signal strength, a second circuit generates a current through a flux cancelling winding that cancels at least some of the flux generated by the power line current.

Abstract: A switching circuit may comprise first and second switch legs and a coupled inductor. The controller may operate the first and second switch legs to control a current flowing through the coupled inductor such that zero voltage switching (ZVS) may be applied to the first and second switch legs. The system may determine a switching event time of a switch in the first switch leg, and determine a switching node voltage rise event time of the first switch leg based on a voltage measured at a switching node of the first switch leg. The controller may drive one or more switches using PWM signals. For example, the controller may drive one or more switches based on determining, for a switching instance, a phase difference between a first PWM signal and a second PWM signal for generating a ripple current for ZVS.

Abstract: Various implementations described herein are directed to a methods and apparatuses for disconnecting, by a device, elements at certain parts of an electrical system. The method may include measuring operational parameters at certain locations within the system and/or receiving messages from control devices indicating a potentially unsafe condition, disconnecting and/or short-circuiting system elements in response, and reconnection the system elements when it is safe to do so. Certain embodiments relate to methods and apparatuses for providing operational power to safety switches during different modes of system operation.

Abstract: Various implementations described herein are directed to a method for determining an order of power devices connected in a serial string. A command is transmitted, to at least one first power device of a plurality of power devices, to change an output electrical parameter. At least one electrical signal is caused to be transmitted from at least one second power device of the plurality of power devices. At least one measured value responsive to the electrical signal is received from at least one of the plurality of power devices. A determination is made, by analyzing the at least one measured value, which ones of the plurality of power devices are ordered in the serial string between the at least one first power device and the at least one second power device.

Abstract: A no-contact switch is provided that is configured to change the state of a power converter in a photovoltaic system. The no-contact switch has a mechanical section that is movable from a first position to a second position and which may include a rotary dial or a sliding tab. The mechanical section may be mounted to and penetrate an enclosure. Each of the first and second positions may please a different area of the tab or dial in proximity to a sensor. The sensor may be placed in an interior of the enclosure, and may be configured to sense the change of position of the mechanical section. A controller may be configured to read the signal that the sensor outputs and, according to the signal, determine an electrical state of the power converter and/or change the state.
