DC Power Supply Basics Tutorial - summary or tutorial about the
basics of DC power supplies, PSU, detailing linear and switching
types and their advantages and disadvantages. Power supply
technology tutorial includes: Power supplies or power supply
units, PSU, form an essential part of very many items of
electronics equipment. The most common form takes in AC power
from the mains supply and delivers a DC voltage to the item
requiring power. Accordingly power supplies are widely used in a
variety of forms - some large supplying high levels of current,
other power supplies, much smaller providing lower levels of
power. Power supply basics The aim of a DC power supply is to
provide the required level of DC power to the load using an AC
supply at the input. Different applications require different
attributes, but more often than not these days DC power supplies
provide an accurate output voltage - this is regulated using
electronic circuitry so that it provides a constant output
voltage over a wide range of outpu
