Equations for the Average and RMS Load Voltage of Chopper
Q. For a first quadrant chopper operating on a dc voltage v volts, plot the variation of the average load voltage with the duty cycle D.
The equations for the average and rms load voltage are
VLdc = D x C
Table gives the values of average and rms voltages for different values of D.
