TL;DR: It is demonstrated that, with a careful design of the converter, the filter capacitances can be made small enough so that film capacitors may be used, and the converter mean time between failures can bemade as high as that of the solid-state lamp.

TL;DR: In this paper, a streetlight LED application is covered, using the Integrated Buck-Flyback Converter developed in previous works, which performs power factor correction from a universal ac source, as well as a control loop using the LM3524 IC, which allows PWM dimming operation mode.

TL;DR: In this application, the offline integrated buck-flyback converter is used to provide power-factor correction from a universal ac source and a control loop using the LM3524 IC has been implemented for testing the feasibility of Enabling pulsewidth modulation dimming mode.

TL;DR: The integrated buck-flyback converter (IBFC) is investigated as a good solution for implementing low-cost high-power-factor ac-dc converters with fast output regulation and it is shown that, when both buck and flyback semistages are operated in discontinuous conduction mode, the voltage across the bulk capacitor is independent of the output power.

TL;DR: The high-frequency series PWM dimming technique is introduced, which overcomes all the challenges faced when developing PWMDimming capabilities in low slew-rate constant-current fixed-frequency-controlled converters and offers all the advantages of PWMdimming over analog dimming while maintaining good efficiency.
