LED electronics, harmonic issues and augmenting Standards

This paper presents a comprehensive analysis of the harmonics generated by the driver circuitry of reputed international brands of energy efficient LED (Light Emitting Diode) lamps. The paper explains how the proper selection of the combination of LED lamps by the consumers can help reduce the harmonic emissions. This also deliberates the importance of phase angle of each harmonic component in managing the harmonic emissions and how it could be a useful tool for driver circuit manufacturers as well as the Standard developers.
