Abstract: WHEN SINGLE-PHASE voltage regulators are connected in delta or in open-delta on 3-phase systems, the regulator is excited by the line-to-line voltage, but it transmits line current. For this ...

The loop has DC gain equal to 107 dB, UGF equal to 15MHz, phase margin equal to 66 degrees, and gain margin of 12 dB. High UGF and sufficient phase margin restore the desired output voltage quickly ...
