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 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 کاملImplementation of One-cycle Control for Switched Capacitor Converters
An extension of the one-cycle control (OCC) method for switched-capacitor (SC) converters is proposed in this paper, featuring a fast dynamic response, wide line and load operation ranges, and simplicity in implementation. To illustrate the operation principle of this nonlinear control method and to demonstrate its simplicity in design, a dual-phase unity gain SC converter is examined. A new co...
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 کاملAccelerated Ageing of Aluminum Electrolytic Capacitor
Electrolytic capacitors are extensively used in filtering and power decoupling in power electronic converters. Low cost and high energy density of these capacitors make them popular. However, these capacitors degrade with age due to heating and evaporation of electrolyte. This process may take about 2 to 7 years depending on the application, ambient conditions and capacitor construction. This p...
