Converter parameters
(OP)
For the full wave three phase bridge thyristor converter there is a well known relationship between the RMS value of AC line current and a DC current: I(L)=0.815xI(d). Please advise what is the relationship between the above parameters for the IGBT-based PWM three phase bridge converter?





RE: Converter parameters
Sqrt3*U*I(L)* cosphi = Ud * Id
with U beeing the lini-to-line input voltage
With proper control and modulation you can choose any Ud above Sqrt2*U and the displacement power factor cosphi as you like
