Design of alternating current voltage–regulating circuit based on thyristor: Comparison of single phase and three phase

open access: yesMeasurement + Control, 2020
The voltage sag problem in a power grid can be solved by a voltage regulator. In this study, the voltage regulator based on thyristor was used to compensate the single-phase and three-phase voltage of voltage sag fault, so as to recover the normal level ...

Design Voltage Regulator for Synchronous Generator [PDF]

open access: yesEngineering and Technology Journal, 2008
As the loud on an alternator is varied, its terminal voltage is also found tovary. This variation terminal voltage is due to voltage drop in armature(resistance, leakage reactance) and armature reaction, therefore thisresearch aim to design voltage ...

Suppression of Second-Order Harmonic Current for Droop-Controlled Distributed Energy Resource Converters in DC Microgrids [PDF]

open access: yes, 2020
Droop-controlled distributed energy resource converters in dc microgrids usually show low output impedances. When coupled with ac systems, second-order harmonics typically appear on the dc-bus voltage, causing significant harmonic currents at the ...

Overview on Latch-Up Prevention in CMOS Integrated Circuits by Circuit Solutions

open access: yesIEEE Journal of the Electron Devices Society, 2023
In CMOS chips, the wider layout rules were traditionally applied to overcome latch-up issues. However, the chip area with wider layout rules was often enlarged, and in turn the chip cost was also increased.
