摘要： A device, system, and method is disclosed for improving safety of a power system. For example, a differential current may be detected using at least one sensor by temporarily enabling sampling of current flowing through one or more conductors. Additionally, current flow may be temporarily altered in order to sample current in a system. The measurements may be handled locally and/or remotely and appropriate actions may be taken to enhance the overall safety of the system.

摘要： Systems, apparatuses, and methods are described for a transformer supporting two or more sets of windings electrically connected to different voltage levels. Use of stress control materials or composite materials (comprising a matrix and filler) may direct electrical fields caused by the different voltage levels to have a lowered electrical field amplitude.

摘要： A method for testing a photovoltaic panel connected to an electronic module. The electronic module includes an input attached to the photovoltaic panel and a power output. The method activates a bypass to the electronic module. The bypass provides a low impedance path between the input and the output of the electronic module. A current is injected into the electronic module thereby compensating for the presence of the electronic module during the testing. The current may be previously determined by measuring a circuit parameter of the electronic module. The circuit parameter may be impedance, inductance, resistance or capacitance.

摘要： A power system and a power method for a power system that includes a first power source operatively connected to an input of a first power device. The power system also includes a switch unit having a first input operatively connected to the output of the first power device. The power system further includes a second power source operatively connected to a second input of a second power device. A second output of the second power device connects to a second input of the switch unit, wherein a third output of the switch unit provides an output parameter responsive to at least one of the output of the first power device and the second output of the second power device.

摘要： A method for a power system having a string of a plurality of power sources connected across a power device includes connecting a plurality of safe voltage units having safety switches connected respectively across each of the power sources. The method includes sensing a plurality of parameters of the power sources, and monitoring for a signal transmitted from the power device. Each of the safety switches is activated to be OFF responsive to detecting the signal within a predetermined time period. Upon not detecting the signal from the power device within the predetermined time period, a safe mode of operation of the power system is entered in which the voltages of each of the power sources is reduced to a voltage level less than a predetermined voltage level by turning the safety switches ON.

摘要： Systems, apparatuses, and methods are described for power conversion. Dampening circuitry may be operatively connected to power converter circuitry to reduce accumulated charge during different portions of an alternating current (AC) cycle. The dampening circuitry may be arranged for soft switching of the converter circuitry to reduce voltage or current spikes and noise.

摘要： A circuit for combining direct current (DC) power including multiple direct current (DC) voltage inputs; multiple inductive elements. The inductive elements are adapted for operatively connecting respectively to the DC voltage inputs. Multiple switches connect respectively with the inductive elements. A controller is configured to switch the switches periodically at a frequency sufficiently high so that direct currents flowing through the inductive elements are substantially zero. A direct current voltage output is connected across one of the DC voltage inputs and a common reference to both the inputs and the output.

摘要： Methods for arc detection in a system including one or more photovoltaic generators, one or more photovoltaic power devices and a system power device and/or a load connectible to the photovoltaic generators and/or the photovoltaic power devices. The methods may measure voltage, current, and/or power delivered to the load or system power device, and the methods may measure voltage noise or current noise within the photovoltaic system. The methods may periodically, and/or in response to detecting noise, reduce an electrical parameter such as current or voltage in order to extinguish an arc. The methods may compare one or more measurements to one or more thresholds to detect arcing, and upon a comparison indicating that arcing is or was present, an alarm condition may be set.
