摘要： A photovoltaic (PV) module safety shutdown system includes a module-on switch coupled with a PV module coupled with an alternating current (AC) mains panel through an inverter. A system monitor couples with the module-on switch and with the AC mains panel and generates a system-on signal. A module discharge switch couples with an inherent capacitance of the inverter and with the system monitor. The module discharge switch discharges the inherent capacitance, by coupling the inherent capacitance with a discharge element, in response to the system monitor not generating the system-on signal. In implementations a module short switch shorts the PV module in response to a passage of a predetermined amount of time after the module discharge switch is switched on. The module-on switch, module discharge switch, and module short switch may be included in a junction box of the PV module and coupled with the system monitor through multiple opto-isolators.

摘要： There is described a method for driving paralleled electronic switches via a drive signal processing circuit (1) connected to respective driver circuits (5A, 5B) associated with said electronic switches (7 A, 7B). During the turn-off intervals of the electronic switch, the driver circuit sends a fault signal to the drive signal processing circuit. During the turn-off intervals of the electronic switch, the driver circuit masks the fault signal coming from the drive circuit of the electronic switch.

摘要： An electronic device with a plurality of keys which correspond to a plurality of standard voltages respectively comprises a voltage generation module, a detection module, storage, an acquiring module, a comparison module, and an extraction module. The voltage generation module with an initial voltage decreases the initial voltage to the standard voltage corresponding to the pressed key. The detection module detects whether the current voltage of the voltage generation module is equal to the initial voltage. The storage stores the current voltage as a reference voltage when the current voltage is not equal to the initial voltage. The acquiring module acquires a current voltage of the voltage generation module after a predetermined time. The comparison module compares the acquired current voltage with the reference voltage. When the acquired current voltage is equal to the reference voltage, the extraction module executes an operation corresponding to the reference voltage.
