How to adapt a DAB-based converter model for RT Box 2 using the Nanostep solver?

PLECS

Hi,

I am working on a HIL implementation using an RT Box 2, and I would like to adapt a Dual Active Bridge (DAB)-based converter model to run with the Nanostep solver.

The topology I want to implement is shown in the attached image. It is a DAB-derived isolated DC-DC converter in which the primary side is similar to a conventional full-bridge stage, while the secondary side includes additional switching cells, clamping capacitors, inductors, and an output DC bus.

My goal is to use this converter in a real-time HIL setup for my research, where the control algorithm will be implemented externally, and the power stage will run in PLECS RT Box 2.

I would like guidance on modifying the DAB block to correctly include the additional secondary-side switches, clamping capacitors, and inductors.

Any recommendations, examples, or modeling guidelines would be very helpful.

Thank you in advance for your support.

Best regards,
Henry
