Diode has become the most widely used device in the field of power electronics because of its unidirectional conductivity. It is very important to study the working principle and model of diode. This article first expounds the forming principle of P-N junction and PIN junction, then respectively the diode of the steady state and transient state model was established, and then separately from the Infineon website to download the IDW100E60 diode model and discrete device based on ideal diode model LTspice simulation, comparison and analysis the differences in the waveform, and the possible reasons for error is given. Finally, buck circuit was built, and the reverse recovery characteristics of the diode model were observed in the actual circuit.
