How does a 3 phase inverter work?

However, most 3-phase loads are connected in wye or delta, placing constraints on the instantaneous voltages that can be applied to each branch of the load. For the wye connection, all the “negative” terminals of the inverter outputs are tied together, and for the detla connection, the inverter output terminals are cascaded in a ring.
