pulse rectifiers

Hello guys, im trying to simulate single-phase voltage pulse rectifier (also single phase current pulse rectifier) like these:

Im new in using orcad - its for my class of simulation, so can someone please  point out mistakes im doing so i can make PWM modulation and get some results? Also im not sure if im using good thyristors for control in these schematics..

 

Every help will be apreciated :-) thx a lot

In both the designs, you have not connected the gate drive. You may want to connect VPULSE source from sources library and connect those to complete gate drive of thyristors. 

You also need to design VPULSE (inputs source) parameters. Also, it seems that you have selected a wrong source type - Is your goal is to simulate sinusoidal input voltage? If yes, then select VSIN instead of Vpulse.
