Power Supply Design in a Modular LED Dance Floor
نویسندگان
چکیده
The Washington University in St. Louis IEEE student branch are designing a next-generation LED dance floor that synthesizes color, music, and touch in a way that has not been done in any other device. The device is being designed with modularity and expandability as key features and therefore a solid, reliable power system was needed. This report focuses on the project’s power distribution and regulation design including how the use of switching voltage regulators increased the power supply’s efficiency from 37% to 75%, how delivering fused 120V AC power to the modules instead of low-voltage AC or DC reduced cost, complexity, and weight, and how the end result was a reliable, robust, and efficient power system that enables assembly of the dance floor in any shape and size.

A Direct Power Feeding System for AC Railway Networks Using Modular Multilevel Converter
Abstract Traditional railway power supply systems impose substantial power quality problems (PQ) on the utility network, such as unbalance, harmonics and a large amount of reactive power. This paper proposes a topology based on three-phase to single-phase modular multilevel converters (MMC) to obviate these problems. The MMC based traction substations (TSS) are connected directly to the utili...

In fact, any educational modular is a set of knowledge, attitudes and skills which by using them it can be possible to do ...
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...

Linear AC power supplies can be replaced by their nonlinear switching counterparts due to the lower voltage drops and higher efficiency and power density of switching-mode inverters. Multilevel cascaded H-bridge (CHB) converters are the preferred inverter structure because of modular configuration, control, and protection. The output voltage quality in CHB converters depends on the number of ou...
