基于DSP的智能功放开关电源设计

针对音响功放环保节能的需要，设计一款新型功放开关电源的控制系统，该系统可应用于大型功放系统的DSP控制。详细描述系统的组成结构和软硬件设计。该系统采用TMS320F2812为主控制器，电路结构简化，数字控制功放电源。实验结果表明，该系统具有良好的调节功能，既满足一定控制精度要求。又满足实时性要求，在高端大功率音响功放中具有较大的应用前景。

Design of power supply for intellgent power amplifier based on DSP

This paper designs a new type of the control system of switcing power supply for audio power amplifier,which is used in DSP-controlled power amplifier.The basic frame and the software and hardware design of the system are described.The system uses TMS320F2812 as the main controller,to reduce the hardware circuit structures,and realize the audio power amplifier digital control.The experimental results show that the design has good regulator function,which not only satisfies a certain control accuracy,but als...
