Distorted perovskites for high voltage dielectric capacitors [PDF]
Energy Harvesting and Storage: Materials, Devices, and Applications IX, 2019 There are several mechanisms which have been proposed for the existence of colossal dielectric constant in the class of perovskite calcium copper titanate (CaCu3Ti4O12 or CCTO) materials. Researches indicate that existence of twinning parallel to (100) (001) and (010) planes causes planar defects and causes changes in local electronic structure.

FPGA implementation of impedance-compensated phase-locked loop for HVDC converters
The Journal of Engineering, 2018 The phase-locked loop (PLL) plays a key role in HVDC systems. Recently, a new type of PLL called the impedance-compensated phase-locked loop (IC-PLL) was introduced to compensate for the voltage drop across the AC network's Thevenin impedance, making the

Resistive Shaping of Interconnected Low-Voltage Microgrids Operating Under Distorted Voltages
IEEE Transactions on Industrial Electronics, 2022 Beyond the impacting presence of non-linear loads, low-voltage microgrids also experience low energy efficiency and resonance phenomena when operating interconnected to a distribution grid that suffers from distorted voltages. This paper proposes a model-free control strategy capable of coordinating inverters existing within a dispatchable microgrid ...
