I have been reading some of the posts here on phase converting and current balancing. I've come across one made by "Moray". In his post he states "If you want to be more accurate, balance the convertor while it's running without any load, then add suitable capacitors to each motor so that the convertor remains balanced when each motor is running. I've heard off several people who've done this to ensure they get the motors running as smoothly as possible". I would like to do this very thing so I am able to run more than one machine at a time. Could someone explain how it's possible to add capacitors to each individual machine motor without affecting the others in the circuit. The only way I see to do this is to place the motor capacitors on the load side of a disconnect at the individual machine. This would only allow operation of one machine at a time. I need a way to provide each machine with 3 phase from the converter while maintaining isolation between machines.
