带有3次谐波注入的SPWM波的实现，基于2812的环境，带有死区时间，调制比0.8,N=123-With 3rd harmonic injection SPWM wave realization 2812-based environment with dead time, modulation ratio 0.8, N = 123

用2812的时间管理器，产生不带死区的6路互补的SPWM，通过在2812上已调试成功-The time manager with 2812, resulting in a dead zone 6 with no way complementary SPWM, passed in 2812 has been successful commissioning
