A dual-loop boost-converter LED driver IC with temperature compensation

A Single-Stage LED Driver Based on Interleaved Buck-boost Circuit and LLC Resonant Converter

A single-stage LED driver based on interleaved buck-boost circuit and LLC resonant converter is proposed. The buck-boost circuit and LLC resonant converter are integrated by sharing switches, which can decrease the system cost and improve system efficiency. The input voltage of the buck-boost circuit is half of the rectified voltage, and two buckboost circuits are formed with the two half-bridg...

A Closed Loop Control of Quadratic Boost Converter Using PID Controller

This paper presents an implementation of open loop and closed loop control of Quadratic boost converter using PID controller.  Quadratic boost converter consists of boost converter and fly back converter driven by a single switch. Quadratic boost converter QBC is designed especially for regulating the DC interface between various micro sources and dc-ac inverter to electricity grid. Quadratic b...

A Single-Stage LED Driver Based on BCM Boost Circuit and LLC Converter for Street Lighting System

Analysis and Design of the Integrated Double Buck-Boost Converter as a High-Power-Factor Driver for Power-LED Lamps

The IDBB converter features just one controlled switch and two inductors and is able to supply a solid-state lamp from the mains providing high power factor and good efficiency. And with a careful design of the converter the filter capacitances can be made small enough so that film capacitors may be used. Thus the converter mean time between failures can be made as high as that of the solid-sta...

Buck-Boost LED Driver Using the PIC16F785 MCU

• The on-chip op amp of the PIC16F785 is used to amplify the voltage across the current sensing resistor. This allows a much smaller sensing resistor to be used and reduces power dissipation. • The PIC16HV785 device can be used, which eliminates the requirement for an external 5V regulator when operating from higher supply voltages. • This application has unused analog resources which could be ...
