What is a DC Power Supply?
• A DC power supply is a type of power supply that gives direct current
(DC) voltage to power a device.
• Because DC power supply is commonly used on an engineer‘s or
technician‘s bench for a ton of power tests, they are also often called
a "bench power supply."
Different Power Inputs for a DC Power
Management Subsystem
A DC power supply has two major power inputs:
i. AC Input
An AC input can be rectified and filtered to produce a DC voltage, which
is then applied to a regulator circuit, generating a constant DC output
voltage. The output can range from less than a volt to >1000 volts
ii. DC Input
