TMDSHV1PHINVKIT 的sSoftStartMode(void)源代码中 限定了 Vdc bus总线的电压在380±10V 才进入cNormalInvMode 吗?
if((dwBus_Voltage_Fbk <= (Gui_Bus_Volt_Ref + cBus10V)) &&
(dwBus_Voltage_Fbk > (Gui_Bus_Volt_Ref – cBus10V)))
{
wSysMode = cNormalInvMode;
dwBus_Voltage_Ref = Gui_Bus_Volt_Ref;
wTemp = 0;
return;
}
下面这段代码 中想起到什么作用?
if(dwBus_Voltage_Ref >= (Gui_Bus_Volt_Ref + cBus5V))
{
dwBus_Voltage_Ref -= cBus1V; //Increase the BUS by 1V per 20ms
}
