How to Model a Bidirectional DC-DC Converter in Simulink
A bidirectional DC-DC converter is a core block in EV, BESS, HESS, DC-microgrid and vehicle-to-grid studies. The model should demonstrate controlled power flow in both directions rather than only showing switching waveforms.
Choose the topology
For many research models, a non-isolated bidirectional buck/boost stage is a clear starting point. Define the high-voltage bus, battery/storage voltage, power rating, switching frequency, inductor and capacitor values.
Build the switching model
Implement the two active switches with complementary gate logic and appropriate dead-time. Use voltage and current measurements on both ports and include realistic source/storage impedance when required.
Control both power directions
Use an outer voltage or power loop and an inner current controller. Define the sign convention clearly so positive and negative current correspond to charging and discharging or boost and buck operation.
Results for a research page
Show DC-bus voltage, storage voltage/current, inductor current, power flow, duty ratio, transient response and efficiency or losses. Compare charging/discharging transitions and load/reference steps.
Need the full model, code or a customized research version?
Send your title, abstract or base paper. We can review the model scope, software version, comparison cases and required plots before implementation.

Frequently asked questions
Yes. A bidirectional topology and controller can reverse current or power reference so the same stage operates in buck and boost directions.
Start with a stable switching baseline, then add MOSFET/IGBT/SiC device losses, dead-time or thermal effects if the research objective requires higher fidelity.
