Platform assembly and operation
As a bidirectional DC-DC converter, electric energy could be transferred from high-voltage port to low-voltage port (Battery charge mode, BCM), or from low-voltage port to high-voltage port (Battery discharge mode, BDM).
The hardware configurations and parameter configurations are different for different operating modes.
The following section describes how to run the converter in all working modes.
- Battery charge mode (BCM)
- Hardware connections
- Plug HVP-56F83783 into the expansion card socket on the power board.
- To supply DC voltage, connect the DC source on the high-voltage port.
- Connect the load on the low voltage port.
- Connect isolated SCI interface J2 on HVP-56F83783 to the PC through a USB-Mini-B cable.
- Powering the boards: Power the platform by powering up the DC source.
- Control and monitor the system with FreeMASTER:
- Open the FreeMASTER project (Bidir_DCDC_MC56F83783.pmpx) with FreeMASTER. Figure 4 illustrates the FreeMASTER window.
- Enable the communication between the PC and HVP-56F83783.
- To set up the communication parameters, select Project > Options, under the Comm tab.
- Select the port used by CP210x and set the baud rate as 115200.
- To select the correct symbol files, click the … button under the MAP Files tab.
- Click OK and save the configuration.
- Click the Go icon and start the communication. Once the communication is established, click the Stop icon to close the communication port.
- After the FreeMASTER communication is established, click the drop-down menu of the gsDCDC_Drive.gu16WorkModeCmd command and select BCM.
- Click the drop-down menu of the bDCDC_Run command and start/stop the converter.
- The low voltage port voltage ranges from 40 V to 60 V. You could change the low voltage port voltage by changing the macro: VLV_BCM_REF (Bidir_DCDC_MC56F83783 > source > bidir_dcdc_ctrl.h). The default low voltage port voltage is 56 V.
- Open the FreeMASTER project (Bidir_DCDC_MC56F83783.pmpx) with FreeMASTER. Figure 4 illustrates the FreeMASTER window.
- Hardware connections
Battery discharge mode (BDM)
- Hardware connections
- Plug HVP-56F83783 into the expansion card socket on the power board.
- To supply DC voltage, connect the DC source on the low-voltage port.
- Connect the load on the high-voltage port.
- Connect the isolated SCI interface J2 on HVP-56F83783 to the PC through a USB-Mini-B cable.
- Powering the boards: Power the platform by powering up the DC source.
- Control and monitor the system with FreeMASTER:
- Open the FreeMASTER project (Bidir_DCDC_MC56F83783.pmpx) with latest FreeMASTER and enable the communication between the PC and HVP-56F83783.
- After the communication is established, click the drop-down menu of the gsDCDC_Drive.gu16WorkModeCmd command and select BDM.
- Click the drop-down menu of the bDCDC_Run command and start/stop the converter.
