* AC current flows into the rectifier
* Semiconductor devices allow current to pass in only one direction
* Output becomes pulsating DC (can be filtered to smooth DC)

⚙️ Types of Solid State Rectifiers
1. Half Wave Rectifier
* Uses 1 diode
* Converts only half cycle of AC
2. Full Wave Rectifier
* Uses 2 or 4 diodes
* Converts both positive & negative cycles
3. Bridge Rectifier
* Most common type (4 diodes)
* Efficient and widely used
4. Controlled Rectifier (SCR based)
* Output voltage can be controlled
* Used in industrial power control
