SCR Regulated DC Power Supply

SCR Regulated DC Power Supply   Study of output voltage variation, regulation and ripple in open loop (without feedback) 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 filter shunt 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 Features: The board consists of following built-in parts: 24V D.C.
