Hi I am currently doing a project which requires a half bridge rectifier using IPD60R385CP power mosfet. This mosfet is driven by a TC4424AVOA 3A dual High-speed mosfet driver. The pulse signal is generated by a function generator with 200kHz, 50% duty cycle and 100ns rise/fall time. Everything is working fine under a 12V DC power supply (V1), connected to the drain of the power mosfet (U2). However, when I change the power supply to 380VDC, there will be a convergence error prompting me during simulation. My project requires high input voltage of about 380V to 400V. I am using Multisim 14 Pro Edition. Below are my attached files of my schematic circuit and also the datasheet of the power mosfet and mosfet driver. Can anyone help me with this problem?

Hi RR

Is it possible for you to show me what you mean in the multisim?

Thanks
