摘要： A controllable switch, a dual-control switch, and a control system including a controllable switch includes a wireless communication module and a switch component. The wireless communication module is coupled to the switch component. The wireless communication module is configured to send a control instruction to the switch component in response to receiving a switching request. The switch component is configured to switch from a first state to a second state after receiving the control instruction. The first state is one of a turning-on state and a turning-off state, and the second state is the other one of the turning-on state and the turning-off state.

摘要： A microelectromechanical systems (MEMS) switch device including current sensing and overcurrent protection can include a movable plate movable between an open position and a closed position, wherein the moveable plate is moved by applying at least one or more of an electrostatic force and a magnetic force to move the movable plate. The movable plate can include a shunt operable to conduct current when the movable plate is the closed position. An inductive coil electronically coupled to the shunt can detect current conducted through the shunt.

摘要： A contactor apparatus and method for operating the contactor apparatus can include a contactor assembly with a contactor coil operably coupled to a contactor switch. One or more sensors can be provided in the contactor assembly adapted to measure one or more aspects of the contactor assembly. Based upon the measured aspects, a controller can initiate operation of the contactor switch to effectively toggle the contactor switch at a zero-crossing point along an alternating current waveform.

摘要： An Electric Vehicle Supply Equipment (EVSE) powered apparatus includes an input power receptacle capable of receiving the plug of an EVSE device to power the apparatus using power supplied by the EVSE device, and a user-actuatable control that may be used to transition the EVSE device from a connected but not charging state to a charging state after the plug has been inserted into the input power receptacle to cause the EVSE device to transition to the charging state and supply power through the plug. In some instances, one or more output power receptacles may be provided to enable various external electrically-powered devices to be plugged into the apparatus and powered by the EVSE device, while in other instances, the apparatus itself may be an appliance, tool, or other high power device, such that the apparatus is powered directly from the EVSE device.

摘要： Provided are a control system of an electromagnetic relay and an electromagnetic relay. The control system of an electromagnetic relay includes an electromagnet coil, a first resistor, and a first voltage control element. A first terminal of the electromagnet coil is connected to a first terminal of a first power circuit through the first resistor. A second terminal of the electromagnet coil is connected to a second terminal of the first power circuit. The first voltage control element is connected in parallel to the electromagnet coil. The first voltage control element can control the magnitude of the voltage across the electromagnet coil, so that the force to which armature iron is subjected gradually changes.

摘要： A system and method for determining an open or closed position of a magnetically actuated vacuum interrupter. The method includes applying a voltage signal of a known voltage to the actuator over a predetermined period and determining a change in current over time during the period when the voltage signal is applied to the actuator using an output of a Rogowski coil. The method also includes calculating the inductance using the voltage and the change in current over time at a predetermined time during the period and using the calculated inductance to determine whether the actuator and thus the vacuum interrupter are in the open or closed position.
