An Isolated Off-Line High Power Factor Electrolytic Capacitor-Less LED Driver with Pulsating Output Current
One of the most efficient lighting technology is based on light-emitting diodes (LEDs). Common LED drivers with AC-input (50-60Hz) usually require a bulk electrolytic capacitor to decrease low-frequency ripple in the output. However, the critical element that limits the lifespan of the LED driver is the electrolytic capacitor. An isolated off-line LED driver is proposed in this paper, in which ...
متن کاملDesign of Flicker-Free Electrolytic Capacitor-Less Ac-Dc Led Driver
The life of LED driver is mainly dependent on the component used in it. Elimination of electrolytic capacitor is done so that the life of LED driver will increase, if an ac-dc LED driver with power factor correction control is used than the output will be a pulsating current for driving the LED. Since the pulsating current will introduce light flicker that varies double the power line frequency...
متن کاملTorque Ripple Reduction of Electrolytic Capacitor-less BLDC Motor Drive
Brushless DC motors called BLDC are used in many industrial and non-industrial applications today for reasons such as very high efficiency, easy control method and high reliability, and their use is increasingly used in mass production applications, especially home appliances. But these motors require the use of an electric drive, even in constant speed applications. Commercialization of these ...
متن کاملHarmonic Reduction Technique Using Flying Capacitor Based Z Source Inverter for a DVR
The Dynamic Voltage Restorer (DVR) is a commercially available, popular device to eliminate voltage sags and swells in the distribution lines. Its basic function is to inject the voltage difference (difference between the pre-sag and sag voltage) to the power line and maintains the pre-sag voltage condition in the load side. The efficiency of the DVR depends on the performance of the efficiency...
متن کاملFault Prognostic Based on Ar-lssvr for Electrolytic Capacitor
Original scientific paper This paper puts forward a method of fault prognostic based on Autoregressive Support Vector Regression Method (AR-LSSVR) for electrolytic capacitor. Because the electrolytic capacitor is low in cost and large in volume, it is widely used in power electronic circuits. Firstly it introduces the basic model and the fault prognostic algorithm of the AR, LSSVM and AR-LSSVR....
