Abstract: A method and arrangement for determining the effective time of a voltage pulse of phase voltage generated by a frequency converter provided with an intermediate voltage circuit, the voltage pulses of the phase voltage being generated from the upper and lower voltage levels (U DC , 0) of the intermediate voltage circuit, the voltage levels showing a difference in potential (U DC ). The method comprises the steps of generating a first reference voltage (U ref1 ) and a second reference voltage (U ref2 ); scaling the phase output voltage by means of the scaling coefficient (k); comparing the low-pass filtered phase output voltage with the first reference voltage (U ref1 ); detecting a time instant (t 1 ) when the low-pass filtered phase output voltage exceeds the first reference voltage (U ref1 ); comparing the low-pass filtered phase output voltage with the second reference voltage (U ref2 ); detecting a time instant (t 2 ) when the low-pass filtered phase output voltage is lower than the second reference voltage (U ref2 ); and calculating the effective time of the voltage pulse on the basis of the time between the first and the second time instants and a constant term.

Title: Low torque twist-on wire connector
Inventor: LLOYD H KING JR
IPC: C10M107/50
Filed: 2002-12-31
Abstract: An improved twist-on wire connector that permits the user to form the junction ends of wire leads into a low resistance electrical connection with the twist-on wire connector including a self adhering lubricant located along a portion of the interior of the twist-on wire connector. In one embodiment the wires are drawn into the housing by a spiral thread through the twisting action of the wires with respect to housing. As the wires are drawn into the spiral thread, the torque applied to the wires increases until the wires can no longer be hand twisted into the wire connector. Once the wires are drawn into contact with the lubricant the torque resistance, which is a result of frictional resistance between the wires and the spiral thread, decreases while the radial compressive forces between the wires and the spiral thread are substantially unaffected. Consequently, the rate of torsonial resistance decreases allowing the wires to be brought into further electrical contact along a greater length through only hand tightening while at the same time the radially compressive forces on the wires are greater thus ensuring a low resistance electrical contact that remains stable over an extending period of time. Because only a small amount of self-adhering lubricant is needed within the wire connector to provide an enhanced low-resistance electrical connection problems of the self-adhering lubricant accidentally coming into contact with the exterior housing of other twist-on wire connectors is minimized even if not caps are used on the twist-on wire connectors. <IMAGE>

Title: Agro-photovoltaic module
Filed: 2020-09-13
Abstract: The presently disclosed subject matter refers to agro-photovoltaic modules (at times also referred to as agri voltaic modules) designed to increase the productivity use of available area. The agro-photovoltaic module can enable agricultural growth and the production of energy, e.g. by using photovoltaic cell(s), while using the same area (land space, lake, rooftop, etc.), therefore the agro-photovoltaic module can offer a good solution for this issue. This may help overcome legislations/rules in different countries, for example, where land can not be used solely for solar energy cultivation and must be integrated with agricultural purposes. The produced photovoltaic energy is either being used by components of the module or directed to an external electric power system.
