how to calculate the consumption of the rectifier diode?

The rectifier diode is consuming while running, so how to calculate the consumption of the rectifier diode?

The losses of rectifier diode include three aspects:

1. Forward loss: the forward loss power is equal to the product of the forward voltage drop and the forward current;

Second, reverse loss: reverse loss power is equal to the product of reverse voltage and reverse leakage current;

Third, switching loss: due to the existence of junction capacitance, there is reverse recovery current in the diode rectification process, switching loss rate and other products of reverse voltage and reverse recovery current on the diode.

To summarize above, the loss of the rectifier diode is equal to the integral sum of the voltage across the diode and the current in the diode.
