Regelation is the phenomenon in which pressure is used to melt ice into water under 0 degree celsius. Once the pressure from ice is removed, the melted water freezes back to ice. This phenomenon has been showcased by a number of individuals through circling a fine wire around a square block of ice and applying pressure onto it with a heavyweight.
Learn MoreThe parallel-hybrid converter (PHC) based high-voltage dc (HVdc) plant (PHC-HVdc) mandates the injection of additional harmonic-voltage components into its chain-links (CLs) to regulate its output voltage/modulation index (MI). However, these harmonic voltages are restricted to have limited magnitude and their zero crossings must …

Learn MoreA capacitor consists of two separated conductors and its capacitance C represents its "capacity to store charge". Applying a voltage difference V between these two conductors can induce charge +Q on one conductor and Q on the other conductor (so the total charge is zero, that is, the capacitor as a whole is charge neutral), such that:
