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 imbalance between the three legs
to ≤ 2%. Voltage imbalance is calculated according to the NEMA MG1 standard.
