The Losses Of Rectifier Diodes
Sep 28, 2018

The losses of rectifier diodes include three aspects:

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

2, reverse loss: the reverse loss power is equal to the product of reverse voltage and reverse leakage current.

3. Switching loss: due to the existence of junction capacitor, there is reverse recovery current in the diode rectification process, switching loss rate and other diode reverse voltage and reverse recovery current product.

The loss of the rectifier diode is equal to the sum of the voltage on the diode and the current in the diode.
