hello i have some trouble with "TIEVM-HV-1PH-DCAC"

The figure shows a problem when performing Build 2 DC Check.

First, I Set the clearInvTrip : 1 , Rylconnect : 1
then, raise the input DC bus to 50V

And when I increase the output DC source, the boardstatus changes to "overcurrentTrip" as in Capture 2 and it does not go any further.

I don't know what the problem is.

Kim,

What is the res load connecte between the output from the board and DC source?

I feel this could be related to impedance related instability?

What model of the DC source supply are you using?

Hello Manish Bhardwaj

I use wire wound variable resistor with double parallel "200ohms 666W" to make 100ohms and

INPUT of the inverter(DC) : ODA EX400-3

OUTPUT of the inverter(DC/AC) : AMETEK AST 1501

Kim,

Can you reduce the Kp gain of the first PR controller and check again ??
