A New Macro-Model for Power Diodes Reverse Recovery

The power diode is one of the most important elements of the power electronics circuits, because of its role in different converters. The objective of this paper is to find a model for power diode reverse recovery, which can be used in circuit simulation. A simple macro-model for reverse recovery in power diode, that is the most important dynamic effect for power circuit, is developed. Then in order to verify the accuracy of the model, PSPICE simulation and benchmark test results of a power diode in a DC/DC boost converter are given. The simulation and experimental results demonstrates the accuracy of the proposed power diode models. Finally, calculation of the diode power losses due to the diode reverse recovery is given and is compared with simulation and experimental results.
