I am currently using a setup with a FF1400R12IP4 IGBT with a corresponding 2SP0320TA0 gate driver. I have verified that the diodes are working in the intended direction with the description below.
+(red) to gate 2 and -(black) to gate 8 reads: 315 (mV?)
- (black) to gate 2 and +(red) to gate 8 reads: OL (Open loop)
+(red) to gate 5 and -(black) to gate 8 reads: OL (Open loop)
-(black) to gate 5 and +(red) to gate 8 reads: 315 (mV?)
In addition, I have verified that the gate driver is working since it reads ~ -8 V when not commanded, and +15 V when commanded on via a logic signal. To briefly summarize the circuit setup, a + terminal of a capacitor connects to the collector (pin 9 of the IGBT) continuing via the emitter (pin eight) to an electrode. The - terminal of the capacitor is connected to an other electrode. The issue is that the voltage across the electrodes is always high, somehow implying that the IGBT itself is either on or leaking even when there is no logic signal to open the gate. It is worth noting that even outside of this circuit, the IGBT seems to be perpetually on when tested with a 15 V DC power supply. This issue is unlikely to be either the IGBT or the gate driver alone since both components have been replaced but the issue persists.
Any advice moving forward would be appreciated.
Hello everyone,
I would like to set up various chargers in the DC range. Infineon offers chargers in the range 50-350 kW, but unfortunately I don't really know yet which exact components I need for the respective charging station. Is there possibly already an exemplary composition of components for certain charging powers? In other words, a list with the required components / number for a charging station with 50 kW, one for 150 kW and one for 350 kW.
Can anyone in the community help me here?

Show LessI have a yaskawa vfd which has proper incoming voltage but faults out for IGBT short circuit as soon as it’s started. We tried a another old vfd which had been sitting in the storeroom for long time but that gives the same fault?

I tried in in LTspice and in Pspice but with all the troubleshootings for the solver and simulation editing, i couldn`t solve the problem.
I can`t simulate the IGW30N60H3_L2 (just the first cycle in my pulsed simulation)
The error is saying in Pspice: Overflow in device X_U2.XL75xxC.EV2, Convert
INTERNAL ERROR -- Overflow in device X_U2.XL75xxC.EV2, Convert
can anybody help me with this problem?
Thanks
