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 separately uses series linear constant voltage circuit, series regulate constant current circuit and the feedback type contravariant circuit to design direct current constant voltage power supply, direct current constant current power supply and DC-DC converter. 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.
