Derive the expressions of the average load voltage and current in single-phase full-wave controlled rectifier (bridge rectifier) and resistive load. Draw the waveforms of supply voltage, output voltage, output current and thyristor current. In a single-phase full-wave controlled rectifier (bridge rectifier) and resistive load, it is desired to get an average load voltage of 50 V. Determine the firing angle if the ac supply voltage is 150 V. If the average load power is 300W, calculate the average load...

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...
