controlsuit上的PFC程序，这几个K_Vbus， K_Vrms什么意思？他的值是怎么得出来的？512是什么？

K_Vbus=33215;//K_Vbus=(519/512)*32767 = 33215; Voltage will never gets to 512V. So this scaling is fine
 
 
 //K_VrectAvg=24589; //K_VrectAvg=(384.22/2e9)*32767 = (384.22/512)*32767 = 24589
 K_VrectAvg=26226; //K_VrectAvg=(409.8/512)*32767 = 26226
 K_Vrms=26226; //K_Vrms=(409.8/512)*32767 = 26226
 K_VL_fb=26226; //
 K_VN_fb=26226; //
