The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...

Frequency Electronics, Inc. (“FEI” or the “Company”) (NASDAQ-FEIM), a leading provider of precision timing and frequency control products for space and terrestrial applications, is pleased to announce ...

The introduction of large amounts of intermittent renewable power (namely wind and solar) into electrical distribution grids has highlighted the importance of optimizing the frequency regulation ...

To alleviate the drawbacks of quartz oscillator technology, classic microelectromechanical systems (MEMS) materials are now being used to fabricate three-dimensional resonating structures. These ...

The purpose of a phase locked loop (PLL) is to generate a frequency and phase-locked output oscillation signal. To achieve this goal, prior art essentially functioned ...

Inductor-inductor-capacitor (LLC) serial resonant circuits, as shown in Figure 1, can achieve both zero voltage switching on the primary side and zero current switching on the secondary side in order ...

As Australia’s National Electricity Market transitions away from its traditional fossil fuelled generation base towards generation more reliant on wind, solar and energy storage (either BESS or hydro) ...
