3.3.5 Power Cell Bypass (optional)

It is common to halt all the inverter system when the power cell failure occurs. But in "Power Cell

Bypass" method, inverter eliminates only the layer in which power cell failure occurred and keeps

running for high inverter efficiency.

In N5000 series, additional bypassing switches are installed to run the inverter with lowered

voltage for important loads that should not be stopped. So that operator can fix the inverter

without stopping. Additional switches are composed of bidirectional SCRs because the 3-phase

current of the load is bidirectional.
