Delivering 440 W of power typically requires sophisticated resonant topologies, but Power Integrations (PI) has changed that with its TOPSwitchGaN flyback IC family, based on its PowiGaN tech and ...
In the previous articles, we assumed that the descriptions of DC/DC converters were ideal, neglecting the effect of parasitic elements. Thus, it is important to note that inductors have capacitive and ...
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 ...
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, ...
Many power supplies spend much of the time at loads far below their maximum and/or where they have the greatest efficiency, so improved efficiency is frequently required in normal and lower-power ...
Wireless power transfer (WPT) enables device charging without direct physical or wired connections. Resonant circuits are key components of WPT systems that optimize energy transfer from the ...
Generating a high-frequency magnetic field can be quite a challenge due to an assortment of technical issues. At high frequency, magnetic-coil impedance is large. It requires a high-voltage and ...
The efficiency of wireless charging systems is limited by power loss occurring due to frequency changes in the resonant circuits that enable power transfer. These necessary modulations reduce ...
