The power of your power supply is about 13.4 x 50 = 670 Watt, In that case you need to design a 800 Watt power supply. In my experience this kind of power supply is not possible without PFC. And the power supply should use Half Bridge topology. I have seen maximum of 500 Watt power supply...
Use Rotary Encoder to detect exact position of each motor, You can find a rotary encoder inside a mouse. When you rotate the wheel, an optical sensor provides pulses for certain degree of rotation.
OK, Its really different kind of power supply, Buck converters are generally designed for DC-DC conversion. So you have to Rectify the 230V ac first, Because current is low, then Buck converter work at this kind of input voltage. IRF840, IRF830, IRF450 these kinds of MOSFETS could serve your...
So the point is, Somehow the motor is stopped forcefully from out side when the MCU tries to run the motor right?
If this is the situation then the motor should **** too much current from battery which then cause the voltage drop. Am I right?
You said "when I want to stop the motor manually" ..
Is it possible to stop the motor from MCU by disabling the signals? Or you are already stop the motor from MCU. And also is it possible to slow down the speed to very low frequency before stop the motor?
During test condition, this kind of EMI occurs frequently. It would be better if you can isolate the connection optically from PC RS232 To Your test board serial connections.
Hi, First you need to detect the zero cross from the sine wave. In that case you can use one opto coupler to detect zero cross as follows. The output from the Op amp usually goes to an Interrupt pin of uC.
After an interrupt you have to fire the scr withing 9ms (1 ms wasted to detect zero...
