1.4.3 Test Static Operation

Use the following test procedure for forward charging mode operation:

  1. Connect the HV port to the 800V DC source, set the current limit to greater than 2A
  2. Connect the LV port to 12V E-load, set the load current smaller than 84A
  3. Power up the 12V bias power
  4. Gradually increase the HV source to 800V, less than 1V / ms.

Use the following test procedure for backward discharging mode operation:

  1. Connect the LV port to the 12V DC source, set the current limit to greater than 100A
  2. Connect the HV port to the E-load, set the load current smaller than 1.4A
  3. Power up the 12V bias power
  4. Gradually increase the DC source to 12V (Note: the testing in this report is using 9V because the E-load is limited by 600V)
