How to Choose a Bidirectional DC Power Supply (10 Factors)

23 6 月, 2026

EV Charger (BOBC) Power Supply

A practical checklist for sizing a bidirectional, regenerative DC supply.

  1. Voltage class — match your bus (360–2250 V).
  2. Power & current — peak and continuous, per quadrant.
  3. Bidirectional & regen % — confirm true source+sink and efficiency (here 93%).
  4. Dynamic response — rise/fall and transient recovery for your profile.
  5. Accuracy — set and readback F.S. accuracy.
  6. Modes — CC/CV/CP/CR and priority.
  7. Simulation — battery and/or PV needs.
  8. Comms — SCPI, Modbus-RTU, CANopen for ATE.
  9. Scalability — parallel to higher power/MW.
  10. Standards & calibration — CE/IEC 61010, EN50530, ISO 17025.
