SCR Regulated D.C. Power Supply. 
SCR Regulated D.C. Power Supply 

Power Electronic Training Board has been designed specifically for the study of continuously variable SCR Regulated Power Supply. The power supply can be manipulated to operate under different circuit conditions in order to provide insight into the important modes of SCR power supply operation. The output voltage can be varied from 10 to 40 Volts continuously. The power supply can also be used as a stabilised source to feed external load up to 500mA. Internal loads are provided to test the performance in 16 steps. Practical experience on this board carries great educative value for Science and Engineering Students.

Object:

• Study of output voltage variation, regulation and ripple in open loop (without feed back) by varying the load using inductance input filter
• Same as above experiment by using capacitor input filter
• Study of output voltage variation, regulation and ripple in closed loop feed back by varying the load using inductance input filtershunt transistor pedestal control.
• Same as above experiment by using capacitor input filter-shunt transistor pedestal control
• Study of variation in output voltage for different slopes of linear resistance controlled ramp
• Study of line voltage variation (open loop) compensation
• Study of output voltage variation, regulation and ripple in closed loop feed back by varying load-series transistor controlled ramp in differential amplifier mode
