摘要:
本文介绍了一种防火报警系统用的高效率智能型600 W D类音频功率放大器系统的设计. 该系统通过内嵌Linux操作系统管理并可接入大型的防火报警系统. 通过使用基于新型氮化镓功率管的无整流桥型功率因子校正电路,该系统的功率因子达到99.6%,整个系统满载时的效率达90%. 通过采用恰当的脉宽调制器载波频率和Lanczos内插方法简化了采样率转换滤波器、内插滤波器和脉宽调制器的硬件设计.
Abstract:
This paper discusses the design of a 600-watt high efficiency smart class D audio amplification system for fire alarm networks. An embedded Linux effectively manages the system events and provides interface to large fire alarm networks. Bridgeless power factor correction circuits using Gallium-Nitride power transistors achieve a power factor of 99.6%. The efficiency of the whole system is 90%. An FPGA-based all digital PLL simplifies the design of sample-rate conversion filter and interpolation filter.
