The study of power management techniques has increased drastically within the last few years corresponding to the vast increase in the use of portable, handheld battery applications. These power management systems typically contain several LDO voltage regulators that require large external capacitors. The large external capacitors can not be fully integrated in standard CMOS technologies and hi...

The design of new optimal nonlinear voltage regulator for power systems is considered. In the proposed approach, the Hamilto-Jacobi-Belman (HJB), a partial differential equation, is solved using Taylor series expansion of its nonlinear terms. The performance of the proposed controller in a single-machine infinite-bus power system is simulated and the advantages of the nonlinear feedback control...

Three-phase AC-voltage regulatior systems using silicon controlled rectifier (SCR) have been broadly applied in industrial field.This paper introduces a novel design of three-phase AC-voltage regulation trigger circuitry with SCR and STM32 microcontroller, and presents its application in an energysaving design of oil extractor control system. This design employs photoelectric isolation techniqu...

This paper proposes a fully distributed control methodology for secondary control of AC microgrids. The control framework includes three modules: voltage regulator, reactive power regulator, and active power/frequency regulator. The voltage regulator module maintains the average voltage of the microgrid distribution line at the rated value. The reactive power regulator compares the local normal...
