ABSTRACT
A semiconductor diode may be modeled in SPICE by a diode statement in conjunction with a model statement. The diode statement specifies the diode name, the nodes to which the diode is connected, and its model name. In the static model, the diode current, which depends on its voltage, is represented by a current source. The small-signal parameters are generated by SPICE from the operating point. SPICE generates a complex model for diodes. DNAME is the model name, and it can begin with any character; but its word size is normally limited to eight. A rectifier converts an AC voltage to a DC voltage and uses diodes as the switching devices. The output voltage of an ideal rectifier should be pure DC and contain no harmonics or ripples. The rectifier is supplied from a balanced three-phase balanced supply whose per-phase voltage has a peak of 169.7 V, 60 Hz.
