Abstract: Power factor is a measure of how efficiently electric power is consumed. It is the result of phase difference between voltage and current at different stages of power system. It’s the ratio of active power or useful power to apparent power. The apparent power consists of both the active power and reactive power. If the reactive power increase in a ... Show More

Abstract: LED-powered luminaires have the ability to offer cutting-edge features like temperature adjustment and color management. Color shift creates discomfort in human eyes. So it is essential to design a LED driver which will precisely control the color parameters of the LED driver. Precise control of color parameters like CRI, CCT, color intensity is ve... Show More
