We have three phase input and the voltages in the three input is not the same always. Sometimes, one or two or three phase will be off. I would like to connect the phase to output which lies within the range (110 - 290).
Below will be the example,
Phase 1 (290v), Phase 2 (245v), Phase 3 (190v)
I need to select Phase 1 in this case. Ampere rating would be 40A on the selected output.
Did searched in google for single device (circuit / IC) which can does this, not finding one. Any direction would be helpful.
Voltage Reference: (Added)
Voltage reference is to the neutral line. It would be a
4-wire input to 2 wire output with a common neutral line.
Compare the voltage on each phase with a voltage comparator, connect the output with a solid state SSR in the output.
I would need a power supply now that can input from magic three phases and generate DC output. Not finding the right one.
Will that work?
This seem to be a cheaper and reliable solution, without inductive circuits. Please suggest if I have missed something to consider. SMPS - Switch Mode Power Supply (5V).
This is the cheapest solution, if the input voltage is constant. With the varying voltage, the coil does not seem to take a varying voltage. (100-300V).
