In the case of iSWITCH, standard SPS switches are used. The connection method determines if the iSWITCH method is used by SSN. This is illustrated in the next figure with the online demo SSN_iSWITCH_6pulse_rectifier.mdl.
For an iSWITCH model and method to be detected by SSN, the switch must:
- Be alone in its SSN group
- Be interfaced with V-type NIB
- Have no internal snubber capacitor, nor inductance, i.e. the switch must not contain any L-C state.
This is the case for the SSN_iSWITCH_6pulse_rectifier.mdl demo as shown.
When an iSWITCH is detected by SSN, the MATLAB prompt should highlight it as follows:
