    Calculation of the OVP resistor. Please correct if it is wrong or has errors. I will try to derive a formula for calculating the OVP resistor (the one that is on the bottom of the board). Initially, the OVP resistor, for a voltage of 51.7 volts = 47k. For 63 volts = 2.7k. This means 63-51.7 =...
