Show LessHello, I made an inverter, input 150V DC, switching frequency 200kHz, modulation ratio 0.7, load 100 ohms. IGI60F1414A1L is used, and the peripheral circuit parameters refer to the design document. The current situation is that the drive waveform is normal when there is no LC filter. When the LC filter is added, the driving waveform is disordered, as shown in the figure. May I ask what causes it?

Show LessMy question is, can I use Ansyssimplorer software to model the GaN HEMT model? Modeling requires simulation in an inverter driven by a motor, and then purchasing a chip for testing. Excuse me, is this okay?
Show LessHi Experts, Recently I was evaluating the dynamic performance of GaN MOS, the device model is GS-065-030. while doing the double pulse test, I found that the Ids current oscillates badly during switching, which makes it impossible to estimate the switching loss and other parameters. May I ask what could be the cause of this?
The measured waveforms are shown below, the blue Vm channel is the Ids current waveform grabbed using the SSDN-414-010 (10mohm) shunt. The purple color is the waveform grabbed using the current probe at the load inductor side.

Show LessI have ordered a GAN Daughter Card (GS66508T), Can Anyone confirm whether it is Gate Driver only or Gate Driver Plus GAN switches?
Hi,
I’m designing a 7 kW converter in which each switch conducts 30 A RMS. However, when I analyze the Safe Operating Area (SOA) of the IGOT60R042D1 MOSFET, I observe that at 400 V and 10 μs, the device is only capable of conducting 2 A. ¿ Is this correct, or am I mistaken?

Does GaN mosfet not have this device? I need to purchase a gallium nitride chip to be placed in a motor driven inverter. Before doing so, I need to conduct simulation calculations using Simulator, which can only feature model IGBT and MOSFET classes. Excuse me, is there a gallium nitride chip that meets the requirements?
