Hi,

If you have a wye wound brushless generator and rectify it with a 6
diode full wave rectifier, or if you rectify it with a 3 diode half wave
rectifier with the wye common being ground, the voltage of the 6 diode
rectifier will be 1.77x that of the 3 diode rectifier I read, assuming
it is a 1kW generator normally fullwave rectified is it safe to still
extra 1kW of energy using the 3 diode rectifier configuration, or will
the extra current required possibly overload the generator?

Jamie

Probably will not work. Taking 2KW form a 1KW genertor will likely cause
loverload.

Sorry I meant to say:

is it safe to still EXTRACT 1kW of energy using the 3 diode rectifier
configuration


I don't think that can be ansewered without knowing the generator. If you
pulling the same power with at 1/1.77 lower output voltage, the current must
be a factor of 1.77 higher. (by 1.77) Thats ~ 3 times more I2R heating of
the winding in the generator.

If the generator runs cool at 1Kw with the a full wave diode bridge, it
might be worth a shot. If it gets warm - hot to the touch. fagitaboudit.
