Multiple DC-Bus Power Supply Configuration Example
In this example, three DC-bus (converter) power supplies all receive AC input
power and feed the inverter modules for increased output power.
Contactor enable relays from each of the DC-bus power supplies are wired in
series to protect the DC-bus power supply in the event of shutdown fault
conditions.
