What is the function of the rectifier in a basic DC power supply?
What is the function of the rectifier in a basic DC power supply?
- Eliminates fluctuations in the rectified voltage
- Maintains a constant dc voltage for variations in the input line voltage or in the load
- Converts the ac input voltage to a pulsating dc voltage (correct)
- Changes ac voltages based on the turns ratio between the primary and secondary
