This paper proposes a novel electrolytic-free quasi-Z-Source Ćuk LED driver for automotive applications. Compared to the traditional converter, first merit of converter is higher gain, which makes it apt switch between multiple Secondly, proposed combines inherent characteristics load operate in wide range Continuous Conduction Mode (CCM), so inductors can assist energy storage, and only small ...

In this paper, we propose three advanced digital predictive current-mode control (DPCC) algorithms based on a simplified estimation method of duty cycle lost time for asymmetric half-bridge (AHB) LED constant-current driver. They are the peak current mode control(DPPCC) algorithm leading-edge modulation, quasi-valley control(DPqVCC) trailing-edge and quasi-average control(DPqACC) double-edge mo...

A typical LED (Light Emitting Diode) based lighting system is shown in Fig. 1. It is composed of a power source such as your regular wall outlet or a battery, an LED driver, an LED or banks of LED’s, and a lamp or fixture. An LED driver is an electronic circuit or component that processes power from the source into power usable by the LED’s. The driver regulates and controls the current supplie...
