2.5 Equipment Setup

GUID-20240205-SS0I-40WW-HMMK-QTZLPMPPK4H7-low.svg

Use the following guidelines to set up the equipment:

  1. Set power supply #1 for 20 VDC, 8 A current limit and then turn off the supply.
  2. Connect the output of power supply #1 in series with a current meter to J1 (VIN and PGND).
  3. Connect a voltage meter across J1 (VIN) and J1 (PGND).
  4. Connect load #1 in series with a current meter to J3 (VOUT and PGND).
  5. Connect a voltage meter across J3 (VOUT and PGND).
  6. Set electronic load to CC mode at 4A. Turn off load #1.
  7. Connect J5 to the EV2400. Connect J5 to the I2C PORT 2 on the EV2400.
  8. Make sure the jumpers are installed as indicated in IO and Jumper Descriptions.
  9. Turn on the computer and power supply #1. Open the bqStudio software.
    1. Select Charger and click the Next button.

  11. In 16 Bit Registers, VOUT_REG default is 5000mV
  12. Buck Test: Set VOUT_REG to 5V (5000mV), measure

    V(J1(VAC)) = 20 V ± 0.5 V

    I(J1(IAC)) = 1 A ± 0.5 A

    V(J3(VOUT)) = 5 V ± 0.5 V

    I(J3(IOUT)) = 4 A ± 0.5 A

  13. Buck-Boost Test: Set VOUT_REG to 20V (20000mV), measure

    V(J1(VAC)) = 20 V ± 0.5 V

    I(J1(IAC)) = 4 A ± 0.5 A

    V(J3(VOUT)) = 20 V ± 0.5 V

    I(J3(IOUT)) = 4 A ± 0.5 A

  14. Boost Test: Set VOUT_REG to 36V (360000mV), measure

    V(J1(VAC)) = 20 V ± 0.5 V

    I(J1(IAC)) = 7.2 A ± 0.5 A

    V(J3(VOUT)) = 38 V ± 0.5 V

    I(J3(IOUT)) = 4 A ± 0.5 A
