TOKYO--(BUSINESS WIRE)--Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has launched the “GT20N135SRA,” a 1350V discrete IGBT for use in voltage resonance circuits in tabletop IH cookers, ...

A special frequency determined by the values of the resistance, capacitance and inductance refers to the resonance in AC circuits. The resonant frequency point occurs where the inductive reactance of ...

A recently published second-edition book, Resonant Power Converters, put out in 2011 by the IEEE and Wiley, and written by two professors, Marian K. Kazamierczuk and Dariusz Czarkowski, has 600 pages ...

The quest for higher power and greater efficiency in all power supplies never ends, especially when it comes to all heavy-duty converters. Some examples are power supplies used in data centers, ...

For an undamped LC circuit excited by an AC voltage source through simple phaser equations, we come to see that the circuit becomes short circuited at the resonant frequency. However if we analyze the ...

According to the IEEE Standard Dictionary of Electrical and Electronic Terms, power factor (PF) is defined as the ratio of the circuit power (watts) to the circuit volt-amperes. This is described by ...

Researchers at Turku Centre for Biotechnology have invented new tools for decoding and controlling signalling circuits in living cells with flashes of light. In principle, any cellular circuit can now ...
