摘要： A description is given of an apparatus for disconnecting a connection between solar modules of a photovoltaic string. A circuit breaker, a band-stop filter and a supply circuit are arranged in a series circuit between a first and second terminal. The series circuit is configured to conduct a current that includes a DC string current flowing through the photovoltaic string and a high-frequency control signal modulated onto the DC string current. The supply circuit is configured to generate energy to power the apparatus from the DC string current. An AC bypass circuit bridges the circuit breaker in parallel and is configured to conduct the high-frequency control signal. A control unit is configured to operate the apparatus based on the high-frequency control signal. A reverse current diode oppositely polarized relative to an operating current flow is connected in parallel with the circuit breaker or the circuit breaker and the band-stop filter.

摘要： A circuit breaker includes an interrupter configured to selectively prevent a flow of electrical current through the circuit breaker, and an assembly. The assembly includes a housing, an interrupter mechanism, and an arc protection mechanism. The housing includes an opening configured to channel an arc fault discharge generated during an arc fault into the housing. The interrupter mechanism is coupled to the housing and the interrupter, and is configured to move the interrupter between a first position and a second position, wherein the first position prevents a flow of electrical current through the circuit breaker and the second position permits a flow of electrical current through the circuit breaker. The arc protection mechanism is within the housing and is configured to receive the arc fault discharge through the housing and to cause the interrupter to move to the first position in response to the arc fault discharge.

摘要： Low power solutions can be provided in a serial bus system with a logic controller circuit. The logic controller circuit can include analog circuitry that includes a plurality of analog components and trimming circuitry for configuring the analog components. Digital circuitry can be configured to switch between an active mode and a hibernation mode, wherein the hibernation mode consumes less current than the active mode. A voltage regulator circuit can be configured to generate a regulated voltage from a supply voltage. A reset generation circuit can be configured to determine that the supply voltage has reached a first threshold voltage level and enable the voltage regulator circuit. When the regulated voltage has reached a second threshold voltage level and the supply voltage has reached a third threshold voltage level, the digital circuitry can be switched to the active mode.

摘要： The present invention discloses an energy-saving electronic touch switch, comprising a touch sensing module, a power supply module and a switch driving module, wherein the touch sensing module is used for receiving a touch sensing signal inputted by a capacitive touch switch, and controlling the action of the switch driving module according to the touch sensing signal, so as to switch on a power supply circuit for the load; and the power supply module feeds power to the touch sensing module. The touch switch can drive various loads and has a wider range of possible loads including inductive, capacitive or purely resistive loads and high-frequency switch power supply loads, such as energy-saving lights, AC (Alternating Current) motors, LEDs (Light Emitting Diodes) new light sources, common fluorescent lamps, and the like. The energy-saving electronic touch switch overcomes the disadvantages of small load range and weak load capacity of conventional switches. The energy-saving electronic touch switch employs chips with low power consumption such as LDO (Low Dropout Regulator) voltage regulator chips, touch chips, and the like, which can reduce the overall power consumption, wherein the overall power consumption is less than 2.2 mW and the single static overall power consumption is less than 10 mW (measured under an indicator lamp). The energy-saving electronic touch switch simplifies circuits and improves the power supply utilization rate.

摘要： A power circuit is described that includes a switch coupled to a resistive-inductive-capacitive load and a driver coupled to the switch. The driver is configured to detect an emergency event within the power circuit. After detecting the emergency event within the power circuit, the driver is further configured to perform a controlled emergency switch-off operation of the switch to minimize the maximum temperature of the switch during the detected emergency event and switch-off operation.
