“…The other consists of using switching converters, reaching high efficiency and PFC, but these circuits are complex, expensive and generate EMI. Anyway, these topologies are considered the best solution for higher power levels and for operating within the universal input voltage range [2], [3].…”

“…These topologies represent a good solution when unity power factor is not needed, and perform a fast output dynamics equivalent to that of two-stages PFC converters, but reducing the size of the whole converter and therefore, the cost. In addition, the efficiency is usually very high when operating under narrow input voltage range conditions, because most of the power is switched only once or just a small part is switched twice within a switching period [2].…”

Due to the high rise in luminous efficiency that HBLEDs have experienced in the last recent years, many new applications have been researched. In this paper, a streetlight LED application will be covered, using the Integrated BuckFlyback Converter developed in previous works, which performs power factor correction (PFC) from a universal ac source, as well as a control loop using the LM3524 IC, which allows PWM dimming operation mode.Firstly, the LED load will be linearized and modeled in order to calculate the IBFC topology properly. Afterwards, the converter will be calculated, presenting the one built in the lab.Secondly, the converter will be modeled in order to build the closed loop system, modeling the current sensor as well in order to develop an adequate controller.Finally, experimental results obtained from the lab tests will be presented.

This paper presents a design and construction of LED driver circuit for a specific type of high power LED with Class-D zero-voltage-switching (ZVS) series-resonant converter. In the proposed design, the application consists of a 50 W, 50 kHz switching converter, designed to drive a 1750 lm whitelight, solid-state lamp. The efficiency of the resonant power LED driver is considerably higher compared to that of conventional LED resistive drivers. If the DC output voltage is low, the efficiency of converter will be dominated by the efficiency of the rectifier. A prototype of the drive circuit implemented shows a maximum efficiency of 90% in high frequency transformer isolated ac-to-dc series resonant converter with ac line voltage of 220 V rms .

“…In addition, the size of the whole converter is reduced, and therefore, the costs are reduced too. Moreover, the efficiency is usually very high in case of operation under narrow input-voltage-range conditions because part of the power is processed only once, or just a small part is processed twice within a single switching period [3].…”

Due to the high rise in luminous efficiency that highbrightness light-emitting diodes (HB-LEDs) have experienced in recent years, many new applications have been researched. This paper covers a streetlight LED application using the offline integrated buck-flyback converter (IBFC) developed in previous works. In this application, the converter is used to provide powerfactor correction from a universal ac source. A control loop using the LM3524 IC has been implemented for testing the feasibility of Enabling pulsewidth modulation dimming mode. First, the LED load has been linearized and modeled in order to calculate the IBFC topology properly. Second, the converter has been designed and tested at the laboratory. The converter has also been modeled in order to design a fixed-frequency constant-current control. The dynamics of all the stages involved in the closed loop have been taken into account in order to develop an adequate controller. Finally, the experimental results obtained from the laboratory tests are discussed.
