利用大规模专用集成电路SA4828 设计变频器，可以大大降低CPU 的资源占用，简化硬件电路和软件编程。通过对SA4828 进行初始化编程，可以方便地设定变频器的基本参数包括：载波频率、调制波频

率范围、死区时间、最小删除脉宽、看门狗时间常数、输出波形、频率、幅值、正反转控制等。实验表明，由SA4828 组成的变频器，电路简单，操作方便，运行稳定可靠。-Large-scale ASIC the SA4828 design inverter can greatly reduce the CPU resource consumption, and simplify the hardware circuit and software

Pieces of programming. Initialization programming the SA4828, you can easily set the drive parameters include: the carrier frequency, frequency modulated wave.

Rate range, dead time, the minimum delete the pulse width, the watchdog time constant, the output waveform, frequency, amplitude, reversing control. Experiments show that

By SA4828 inverter circuit is simple, easy to operate, stable and reliable.
