Half Wave Rectifier
Converts AC to DC by allowing current flow in only one direction during the positive half cycle. The negative half cycle is blocked, resulting in gaps in the output waveform.
- Uses a single diode
- Output frequency equals input frequency
- Lower efficiency (40.6%)
- High ripple content
Smoothing Capacitor
The capacitor acts as a reservoir, storing energy during the peaks of the rectified waveform and releasing it during the troughs.
- Reduces output ripple voltage
- Increases average DC output voltage
- Improves power quality
- Response depends on load current
