The controlled full wave rectifier is connected to the grid. The rms grid voltage is 230 Volt at 50 Hz. 24 Volt battery will be charged with 15A. An inductor, which is series connected to the battery, is used to limit the current ripple. Only The second harmonics of the output voltage is taken into account. The inductor R/L ratio is 50. The current ripple is allowed to be 4 amp peak to peak. Determine the firing angle and R...
