Performance
The ideal diodes work as intended for the most part - the output voltage is approximately equal to the supply voltage for all voltages >0V.
For lower voltages (Vin < 3V), the voltage drop across the diode is slightly higher than for higher voltages, approximately 0.24V.
The voltage drop across the diode for higher voltages is constant at around 0.07V.
We tested the diodes with a supply voltage of 110V, and drew 1A using the DC load. No significant heating or abnormal behaviour was observed.
Another test that would be useful would be 2 ideal diodes in parallel, power from different sources with slightly mismatched supply voltages. However, we only have 1 high voltage power source.
