An Improved Non-isolated LED Converter with Power Factor Correction and Average Current Mode Control
A new type of high power LED drivers is proposed by adopting an improved two-stages non-isolated configuration. In order to improve power factor and achieve accurate average current control under universal input voltages ranging from 100 Vrms to 240 Vrms, the power factor correction and average current mode control methods operating in continuous current conduction mode are designed and impleme...
متن کاملDesign and Implementation of Power Factor Correction (pfc) Converter with Average Current Mode Control Using Dsp
This paper presents a digital controlling method for power factor correction converter with boost structure, by applying average current controlling operation at a fixed frequency, to be used at 90-265 Vrms line voltage, based on being applied on DSP. This method which is based designing in analogue domain and converting the resulting model in to digital domain will be discussed in this paper. ...
متن کاملAn 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 کاملGeneralized Average-current-mode Control of Single-phase Ac-dc Boost Converters with Power Factor Correction
The dissertation presents a generalized average-current-mode control technique (GACMC), which is an extension of the average-current-mode control (ACMC) for single-phase ac-dc boost converters with power factor correction (PFC). Traditional ACMC is generalized in a sense that it offers improved performance in the form of significant reduction of the current control loop bandwidth requirement fo...
متن کاملAverage Current Control Mode Boost Converter for the Tuningof Total Harmonic Distortion & Power Factor Correction using PSIM
The aim of this paper is to investigate the power factor correction (PFC) of Boost Converter under an average current-mode control. Boost converter topology is used to accomplish this active power-factor correction in many discontinues/ continuous modes. The boost converter is used usually it is easy to implement and works well. In this paper comparative evaluation of different techniques for h...
