Power Factor Correction

280
The power transmission to a factory involves the transfer of apparent power, a combination of active and reactive power. The power factor measures how effectively electrical power is converted into useful work output. The ratio of the real power (KW) that does the work to the apparent power (KVA) supplied to the circuit.

  • Characterization of the maximum output power density.

Main Results:

  • The MADG unit generates a high voltage of ~0.5 V and current of 100 μA at 100% RH.
  • The device delivers electric output (~0.5 V and ~50 μA) even at 15% ± 5% RH.
  • A maximum output power density approaching 120 mW m⁻² was achieved.

Conclusions:

  • The developed MADG demonstrates efficient energy harvesting from moisture adsorption-desorption cycles.
  • The device has practical applications, capable of powering devices like road lamps and driving electrochemical processes.
  • This work presents a closed-loop system for versatile moisture-based energy conversion.
