DC fault behavior of power converters.
| Technology | Fault current breaking capability | Fault current limitation capability |
| Diode rectifiers | No | No | Forced commutated “active” rectifiers using IGBTs, IGCTs, etc. with free wheeling diodes | No | No | Thyristor-controlled rectifiers | At first AC side current zero | No | Isolated DC-DC converters with HF transformer | Within one HF half cycle | Yes |
