I have requirement of variable voltage, variable frequency (45 to 65 Hz) single phase testing application where is the load is mostly inductive (0.2 lag typically) and have in mind a 3-phase to 1-phase VFD.
If the 3 phase input is 400 V, 50 Hz, what will be the maximum 1 phase output voltage?
Will the 3 phase input currents be balanced for 1 phase output current?
Since the 1 ph output load is inductive with low PF, will the VFD 3 ph input PF be inductive or close to 1 ?
The 1 ph output current maximum will be 600 Amps. Do 3 to 1 ph VFD's exist in that current rating?
