Voltage fluctuation and harmonic emission related to light emitting diode lamps

The energy management issue has become crucial at this moment as the power demand has increased rapidly as time goes on. Therefore, a proper usage of energy is more concerned and the energy efficient lighting system had introduced and being widely used to reduce the power demand. However, at the sam...
