Given a half wave rectifier
power electronics
rl and rle loads
input primary voltage
transformer turns ratio
diode is ideal diode
12-0-12 step down transformer
2200uf 25v capacitor
center-tapped
TFXRI/P 230VOLTS
the peak voltage
process of removing one-half the input signal
Half wave rectifier
AC voltage across secondary terminals
current flows through diode during positive half cycle only
Output frequency
rectified wave also completes one cycle
Consider next (second) half-cycle:
AC polarity reverses
Other diode and other half of transformer's secondary winding now carry current
Portions of circuit formerly carrying current during first half-cycle sit idle
Load still “sees” half of sine wave, of same polarity as before
