Design Optimization of a High Power LED Matrix Luminaire
This work presents a methodology for optimizing the layout and geometry of an m× n high power (HP) light emitting diode (LED) luminaire. Two simulators are used to analyze an LED luminaire model. The first simulator uses the finite element method (FEM) to analyze the thermal dissipation, and the second simulator uses the ray tracing method for lighting analysis. The thermal and lighting analysi...
متن کاملDesign and Simulation of a New DC Power Supply Based on Dual Bridge Matrix Converter
A conventional high power DC power supply systems consist of a three-phase diode rectifier followed by a high frequency converter to supply loads at regulated DC voltage. These rectifiers draw significant harmonic currents from the utility, resulting in poor input power factor. In this paper, a DC power supply based on dual-bridge matrix converter (DBMC) with reduced number of switches is p...

i ABSTRACT Nowadays transducers are ubiquitous as interfaces between the increasingly digital world and the real physical world. The same holds for the power amplifiers driving them. This thesis focuses on the design and optimization of high-voltage class-D amplifiers, which are used for driving capacitive piezoelectric actuator loads in active vibration/noise control applications. The main obj...
متن کاملDesign for Low Power HB-LED Lighting
This paper presents an improved power quality converter (IPQC) based power supply design for high brightness Light Emitting Diode (HB-LED) low power lighting. The IPQC circuit uses a Cuk buck-boost converter to operate it in discontinuous conduction mode (DCM) using voltage follower technique for the mitigation of harmonic contents present in the AC mains current. Subsequently reduction in harm...
متن کاملdesign, optimization and analysis of high power amplifier in the ka band
the graphical technique for nonlinear circuits was described that enable us to optimize circuits to obtain maximum output power, maximum efficiency or minimum intermodulation. according to this method a high power amplifier in the ka band was designed. using a nonlinear model of the transistor, optimum slope for load-line was determined so that maximum power at the output was obtainable, then ...
