[Electronic course design] DC adjustable power supply design

Summary:?

The course design includes two parts: circuit design and circuit welding practice. The circuit design is to design a DC adjustable voltage regulator circuit that meets the basic requirements, complete the design scheme and unit circuit design, parameter calculation and device selection, and system hardware circuit design; the circuit soldering practice includes soldering a two-tube flash, a duty cycle and Frequency independent adjustable pulse generator and a radio, and understand the circuit principle.

basic requirements:

1. Design a constant current regulated power supply to meet:

(1) Make a 0 to 15V DC power supply with the integrated chip.

(2) The power requirement is 15W or more.

(3) Measure the ripple factor of the DC regulated power supply.

(4) With overvoltage and overcurrent protection.

2. Circuit welding practice: complete the circuit welding through the circuit diagram, check the circuit, and check whether the welding circuit works.
