To get 208V from two 120V lines, there should be a phase difference of 120°. To get 220V from a 120V supply, two single-phase lines are combined. 208V requires three live/hot lines for three-phase, and two live lines for single-phase. 220V circuit requires two live/hot lines. 208V is obtained only for a three-phase supply.
Sounds like your best bet is to get a 3ph 480V input rectifier, and use an inverter to get the stable 400V output. Somebody better check with manufacturer and determine if that tolerance is absolute, because, a 300KVA, 480V-400V system ain't gonna be cheap.
Voltage in Single Phase Supply System: Single Phase Voltage = 230V (Phase to Neutral) Phase Voltage (VPH) = Line Voltage ÷ √3 = 400V ÷ √3 ≈ 230V Note: The Voltage between Phase and Neutral is known as Phase Voltage (VPH). Voltage in a Three Phase Supply System: Three Phase Voltage = 400V (Line to Line or Phase to Phase)

It is a conversion calculator that converts the power from kilowatts and voltage in volts to current amps. In case you are using the Direct Current (DC), you will be required to enter the power in kilowatts and the voltage in volts respectively in their appropriate cells. For a three-phase generator, the full load current is calculated as I = 1000 × S / (√3 × V). Where, S is the generator rating in kilo-volt-ampere (kVA), and V is the generator rated voltage in volt (V). For a single-phase generator, the full load current is calculated as: I = 1000 × S / V. Try it with this calculator' . Apr 26, 2015. #3. 380V is no different to 433V. You apply 433V Ph→Ph to a star winding you will get 250V Ph→Y point and 250V ∆ is correct. Likewise 660V Ph→Ph to a star winding you will get 380V Ph→Y point. Therefore 380V ∆ is correct. I doubt your working on 660V but if you are be very careful about the meter you use. Stvu.
