Single Stage Single Switch LED Driver with Improved Power Factor Correction and Soft Switching
Light Emitting Diodes (LEDs) with their current performances have been proved to be the most suitable solution for street lighting applications. Nowadays, a topic of interest in this context is the design for electronic driver in order to take the advantage of LEDs performances. However, requirements such as high power factor, long life time, accurate current control and high efficiency pose ch...
متن کاملSingle Phase Converters for Power Factor Correction with Tight Output Voltage Regulation
The flyback converter type single-stage converter and a half wave rectifier with time-multiplexing control (TMC) for power factor correction is proposed. It has the advantage of better magnetic core utilization and better performance for high power applications. The major portion of the input is transferred to the load through ac-dc conversion. And the part of the input power is delivered to th...
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 کاملAn Improvement of Predictive Control for Single Phase Voltage Fed Power Factor Correction Converters
Harmonic contamination and low power factor in power systems caused by power converters have been a great concern. The effect of harmonics in current due to lagging power factor are the increase in current flow in the capacitors which results in additional heating of the capacitors and reduce its life, increased magnitudes of neutral currents in three phase systems, over-heating in transformers...
متن کاملComparative Study of Power Factor Correction Converters for Single Phase Half-Bridge Inverters
Half-bridge inverter is very suitable for singlephase on-line UPS applications because it offers very desirable features. These include fewer active switches, a common neutral connection – not requiring an isolation transformer, and sinusoidal input currents if a power factor correction (PFC) converter is used at the front end. This paper presents a comparative study of PFC converters for singl...
