17. How to select the appropriate power supply for my application?

It is recommended to select a power supply voltage value that is 10-50% higher than the maximum required voltage. This percentage varies by Kt, Ke, and voltage drop within the system. The current value of the driver should be sufficient to transfer the energy required for the application. Remember that the output voltage of the driver is different from the supply voltage, so the output current of the driver is different from the input current. To determine the appropriate supply current, calculate all power requirements for this application and add another 5%. The required current value can be obtained by calculating the formula I = P/V.
