Implementation of power diode in MATLAB
Power diode simulation model:
The module consists of a resistance Ron, an inductance Lon, a dc voltage source VF, and a switch in series. It has two outputs (K and M terminals) and one input (a terminal ), the cathode and measurement signal output terminals of the power diode and the anode terminals of the diode respectively.
Resistance Ron: Internal Resistance of Power Diode
Inductance Lon: inductance in power diode Components
Either internal resistance or internal inductance must be 0
Forward Voltage VF: forward tube pressure drop of power diode components v
Initial current IC: initial current, usually set to 0
Snubber resistance Rs: Buffer Resistance
Snubber capacitance Cs: Buffer Capacitor
When simulating a power diode, the rigid integral algorithm must be used. Generally, the oed23tb or ode15s algorithm is used.
