自己编写的基于dsp2812的spwm程序，程序能实现软启动，从10hz到50hz，经过RC滤波后能出平滑的正弦波。,I have written programs based dsp2812 of spwm, the program can achieve soft-start, from 10hz to 50hz, filtered through the RC can be a smooth sine wave.

软启动程序代码，对国内软启动器的整体框架的详细代码-Soft-start program code, the overall framework of the domestic soft-start code

数字控制的全桥LLC谐振变换器的软启动程序，开关频率从300kHz降为谐振频率(Soft start program of digital controlled full bridge LLC resonant converter, the switching frequency is reduced from 300kHz to resonant frequency)
