Simulation

The plots for voltage have been normalized with respect to Vom, the maximum average output voltage and the plots for line current with respect to Irms,max, which is 0.707E/R. To see the periodic response, key-in firing angle in degrees in the box on the left-hand side and the ratio t in the box on the right-hand side and then click start button. The boxes have default values filled-in.

The statistical details related to the output voltage have been normalized with respect to Vom and those related to the source current with respect to Irms,max. The amplitude of each harmonic in the output voltage has been normalized with respect to E which is the amplitude of the source voltage , whereas the amplitude of each harmonics in the source current has been normalized with respect to E/R. The applet to follow displays the statistical details.

The applet below displays the transient response. As the ratio gets larger and larger, the load current requires larger period to elapse before it becomes periodic.
