THEORY OF OPERATION
L1 and L2 of the single-phase input pass directly through the phase converter to provide
two legs of the three-phase output. The input module charges a DC bus from the input
lines. The output module uses power from the DC bus to generate the third leg of the three
phase output. The third leg is generated to limit voltage unbalance between the three legs
to ≤2%. Voltage unbalance is calculated according to the NEMA MG1 standard.
