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.关键词
