Abstract: Power factor correction rectifiers/inverters with wide input-output voltage ranges are instrumental in applications with widely varying dc voltages such as photovoltaic inverters. Aiming at ...

U.S. startup Quilt has introduced a new three-zone ductless heat pump for residential use, offering independent temperature control across three areas with a single outdoor unit. The system uses R32 ...

Abstract: This article introduces the principles of the talkative power converter/conversion (TPC) in an ac system, demonstrated through its application in a three-phase power factor correction (PFC) ...

Single-phase power factor correction (PFC) circuits—a kind of front-end AC/DC converters—are ubiquitous in a variety of consumer electronic devices, including laptop adapters, LED driver power ...

Grid operator Fluvius says that 80% of all homes, apartments and small businesses in the Belgian region of Flanders, including 89% of all solar panel owners, have now converted to digital meters as ...

While power meters are very handy tools for tracking your cycling performance, mounting and calibrating the things can be a fiddly process. The CycleClick is designed to change that, by mounting on ...
