How to calculate the power consumption of rectifier diode?

The calculation of power consumption of rectifier diode does not have much meaning. It is recommended that you consult the relevant standards and pay attention to the critical parameters of surge current and uniform current. Because the voltage at both ends of the large electrolysis is 0 at the moment of starting up, the current that can pass through the diode or bridge is huge, and you need to pay attention to whether it is within the range allowed in the standards. In addition, when the diode or bridge is working normally, the allowable uniform current will decrease when the diode or bridge heats up, This is the same statement in the standard book. Of course, when DIYER selects the bridge, the margin is very large, and there is generally no problem, so the surge current and uniform current are key parameters that are very important; Common problem 3 of rectifier diode: What are the common parameters of rectifier diode?
