Abstract
Along with technical development, the electricity and electronic instruments
have already been widespread applied in daily, scientific research, study and so on
each aspect. Since the power supply takes the essential energy-supply part of
electrical and electronic instruments, its demand increases day by day, and also been
set a higher request to function, stability and so on each target. The power supply
research has already become the important link to the development of the new
technology and the new equipment. It’s playing the vital role in the impetus of science
and technology development. This design mainly uses series linear constant voltage
circuit to design direct current constant voltage power supply.We must calculate
various each component parameter in the circuits by correlated knowledge and enable
the circuit performance to meet in the design requirements such as the voltage
regulation rate, the current regulation rate, load regulation rate, ripple voltage and so
on.
This design ideas for the 220V, 50HZ electricity fell right through the step-down
transformer AC voltage value, and through the rectifier circuit to alternating current to
direct current, and then filtered through the filter circuit in the exchange of DC
components, the final composition via an integrated voltage regulator The regulator
circuit into a stable DC output. And an integrated voltage regulator ICs with general
small size, light weight, easy installation and commissioning, reliability and stability
of the higher benefits.
