| Abstract: | Fast recovery diode of high power converter was investigated.A novel hybrid fast recovery diode model combined lump charge model and functional model was developed.In the model,the reverse recovery was described by four phases and "inductive effect" was included in the forward recovery.The model was implemented with the circuit simulation software PSIM.The simulation results are consistent with the ratings of product and experimental results,which proves that the model is able to predict forward and reverse recovery process of diode. |
