The board is populated differently for 400-V
and for 800-V testing:
- 400 V:
- RstP = RstN =
68.1 kΩ
- RinAMC = 120 Ω
- 800 V:
- RstP = RstN =
280 kΩ
- RinAMC = 250 Ω
- All resistors used for the switched-in
resistive branch are 0.1% resistors
- RisoN and RisoP are
simulated by HV resistors between DC+ and PE and DC– and PE.
- The measured values of RisoP
and RisoN are read out via the Expression window of the Code Composer
Studio
