Hi,
My English is not very good. I hope you will excuse me for that.
There is a paragraph in the RT Box manual:
“The power modules supported by the Nanostep solver can be found in the
’Nanostep’ category of the PLECS components library. At least one Nanostep
power module must be present in the model to use the Nanostep solver. To run
the power module on a Nanostep solver, the Configuration parameter of the
power module must be set to ’Nanostep’.”
And there is at least one inductor in all the modules in the ’Nanostep’ category.
I want to know that how to use the Nanostep solver if I do not need the inductor, such as the typical structure of wireless power transfer (WPT) system with series-series (SS) compensation topology?
(from
Analysis of the Influence of Compensation Capacitance Errors of a Wireless Power Transfer System with SS Topology)
To use the Nanostep solver, you must use a component from the Nanostep section of the PLECS library. It will not work with discrete components such as MOSFETs and inductors. All Nanostep topologies currently require at least one inductive element.
The topology most similar to the WPT system you show is the “CLLLC Converter” in the Nanostep section of the PLECS library. You can enable and disable various component in the resonant tank, except the magnetizing inductance and primary side leakage inductance. You could try to set the primary leakage inductance to a small non-zero value, such that it does not influence the converter behavior.
The actual value depends on the other parameters of the circuit. There will be a warning of the parameter will compromise the stability of the Nanostep solver.
Thanks for your reply.
Excuse me, is there any possibility that the nanostep solver can be used without the nanostep library in the near future?
The team at Plexim will add additional Nanostep topologies over time. All new topologies will be implemented in pre-configured Library blocks, such that the component fully describes all information needed to configure the real-time solver. There will not be a workflow where one can construct an arbitrary topology with other components from the PLECS library.

I understand. Thank you very much.
