Understanding Power Supply Units - Post-Session

Front

What is a power supply unit (PSU)?

Back

A power supply unit (PSU) is a device that supplies power to a computer by converting electrical power from an outlet.

Front

Explain the basic function of a PSU.

Back

The basic function of a PSU is to convert and supply electrical power to a computer's components.

Front

What are the main types of power supply units?

Back

Linear, Switching, Uninterruptible (UPS), Programmable, AC-DC, DC-DC.

Front

Describe the difference between linear and switching power supplies.

Back

Linear power supplies use linear regulation and are less efficient, while switching power supplies use high-frequency switching for higher efficiency.

Front

What component in the power system units rectifies the input voltage?

Back

diode

Front

What is the role of a transformer in a power supply?

Back

The role of a transformer in a power supply is to change voltage levels.

Front

How does a power supply convert AC to DC?

Back

A power supply converts AC to DC by rectifying, filtering, and regulating the voltage.

Front

What are the key specifications to consider when choosing a PSU?

Back

Wattage, efficiency rating, connectors, form factor, protection features

Front

Voltage regulation in power supplies

Back

Voltage regulation is the ability of a power supply to maintain a constant output voltage despite changes in input voltage or load.

Front

What is the significance of efficiency ratings in PSUs?

Back

Efficiency ratings in PSUs are significant as they reflect the power conversion efficiency, impacting energy consumption, cost savings, and system reliability.
