What is the main difference between a rectifier and an inverter in power electronics?
A rectifier converts AC (Alternating Current) → DC (Direct Current). It is used in power supplies, battery charging, and DC motor drives. Example: diode bridge rectifier.
An inverter converts DC → AC. It is used in renewable energy systems (solar PV, wind), UPS systems, and variable-frequency drives. Example: PWM (Pulse Width Modulated) inverter.
