By using a 2 phase to 3 phase converter circuit, it is possible to efficiently utilize a two-phase power supply and generate a three-phase power supply. This can be particularly useful in situations where only a two-phase power supply is available, but a three-phase power supply is required for running machinery or other equipment.
And there are rotary phase converters that use a larger three phase motor running on single phase. Using a capacitor on one phase will probably be affected by load. Voltage and/or current-operated start relays for single phase motors are available (to disconnect starting caps), and should work fine in this situation.
A capacitive power supply or capacitive dropper is a type of power supply that uses the capacitive reactance of a capacitor to reduce higher AC mains voltage to a lower DC voltage.
The operating current at this load when there is 3 phase supply is 7 A approximately at each phase. Currently, I am trying to implement the 2 phase to 3 phase conversion using capacitors when there is a phase failure. In this process, I used a 50 uF capacitor for starting and 2 parallel connected 36 uF capacitors for running the motor.
That’s where a 2-phase to 3-phase converter circuit comes in. This circuit is designed to convert the two-phase power into three-phase power. It does this by using various components, such as capacitors and diodes, to create the necessary phase shift and balance the power distribution.
You might try a smaller capacitor. 8 amps on a 440V circuit is 55 ohms, and a capacitor with that reactance at 50 Hz is 57 uF. So maybe try one of the 36 uF capacitors and see if the currents are closer to being balanced. There are static phase converters that use capacitors (and perhaps resistors) to get a close approximation of three phase.
