Wirewound Resistors
There is something important that you need to know. The resistors might be increasing too much the Thevenin DC resistance as seen from the primary coils. If this resistance is too high, the voltages drop at the primary coils do not necessarily follow the power supply voltage.
I would like you to do the following with the power supply you built with the Arduino circuit; replace the primary coils with dummy resistors and record the voltage waveforms. If the recorded voltage is a nice step sinusoidal voltage, then the pure resistor used as a voltage divider is not a good option. You will need to use wirewound resistors. And, that seems to be the case based on the patent’s sketch.
