Answer to Question #56001 in Physics for irebami

Question

All of these stages are involved in the conversion of AC to a DC power supply except _________
Transformer
Rectifier
Filter
Thyristor

Answer 1

Some steps in the conversion of AC to a DC power supply:
Use a transformer to step down the output from high-voltage AC to low-voltage AC. Electrical current enters the primary coil of the transformer and induces a current in the secondary coil, which has fewer coils, resulting in a lower voltage. Little power is lost in this process because the amperage increases in relation to the decrease in voltage.
Run the low-voltage AC through a rectifier. A rectifier usually consists of 4 diodes arranged in a diamond shape - a type called a bridge rectifier.
An essential part of an AC-DC power supply circuit is the filter, used to separate the residual AC (called the “ripple” voltage) from the DC voltage prior to output.
Answer: Thyristor
