Simulation of boost converter using SiC MOSFET in LTspice

I am trying to simulate boost converter using SiC MOSFET (MOSFET MODEL = G2R1000MT17D). The boost converter specifications are:

1. Vin = 200 V
2. Vout = 400 V
3. Fsw = 150 kHz

When simulating the above converter my simulation is not running. Kindly help me to figure out where I am going wrong[![LTspice schematic][2]][2]

• Where is your V(out) node? Sep 14, 2021 at 7:04
• Hi andy thanks for asking The Vout node is across the resistor 320 ohm. Sep 14, 2021 at 10:21
• I think you would change ... .options abstol=0.1 (? absolute tolerance on voltage = 0.1 V) ... .IC v(vout)=400 (ok) ... and add .IC i(L1)=2.5 ... .tran 0 5m -- proceed by little step time (5 ms, max internal step 1ns) save intermediary results and continue simulation ... it works for me with microcap v12.

• Sure Antonio i will try and let you know Sep 14, 2021 at 14:51
• @Vengatesh The reason Andy asked about V(out) is because you have an .IC condition for a node named OUT, but there's no such label attached, anywhere. Therefore your .IC has no effect. Try ading ic=380 to the capacitor, maybe also rser=10m. It might help to add rser=10m rpar=10k to the inductor, rser=10m cpar=1m to the voltage source, add a capacitor across the SiC with 100p rser=100. There's not much else to do since the library that I have (from genesicsemi.com, Cree needs registration) is encrypted. Sep 14, 2021 at 15:36
