Can anybody tell me how can I set the required firing angle using VPULSE source in orcad for the thyristor '2N1595' in the Single phase half wave and, full wave controlled rectifier circuit in orcad ?! I have never worked with thyristors or VPULSE in combination in the Orcad. It is a special case of VPULSE. It should never be used in a frequency response study because PSpice assumes it is in the time domain, and therefore your probe plot will give you inaccurate results. B. PSpice allows you to quickly create the required Sine source SPICE model for a realistic simulation by easily defining the type and signal value. The input is equal to a For the meaning of transient source properties, refer to the I/V (independent current and voltage source) device type syntax in the Analog Devices chapter in the online PSpice Reference Guide.
