volatile long VfbSetSlewed = 2093568; // Slewed set point for the FB voltage loop - start from 4V
volatile long VfbSlewRate = 25600; // FB Slew rate adjustment
volatile long phase = 0; // FB phase command
int16 dbAtoP_leg = 20, dbPtoA_leg = 20; // Dead band adjust for the two legs
请问上述 给定的参考电压 VfbSetSlewed = 2093568 怎么会是从4V开始呢 还有死区时间int16 dbAtoP_leg = 20中，20指的是多少时间 初学者 请指教 谢谢哈
