In this lab, the output current
control loop is closed. In this Lab, using the electrical load(constant voltage
mode) to emulate the battery connection on secondary side.
- Run the project by clicking
the Resume button in the Tool Bar
- Set the CLLLC_iSecRef_Amps
below 5 A during start up
- Increase the input PRIM DC
voltage from 0 V to 400 V
- Clear the trip by writing "1"
to the CLLLC_start variable in the Watch window as shown in Figure 1-4, this closes the voltage loop and the converter performs soft-start
until the output voltage ramps up to 48 V
- Next, test the close loop
operation by varying CLLLC_iSecRef_Amps in the Watch window
