Why is there a negative current through a diode?
Last Updated 3 years ago

The condition for a diode to change state from Closed to Open is when the current in the diode falls to zero or below. In real-time simulations, we use a fixed discrete time step, making it impossible to estimate exactly when the diode should go in an off state. For this reason, we may observe a negative current in only one simulation step.

This means that if the current in the diode is negative in only one simulation step, the diode will be Open in the next simulation step, and current in the diode will be zero. 

If the current in a diode is negative for more than one simulation step consecutively, we suggest you contact our support team (
