Q:Use 7812 to make a positive 12V DC power supply Is 220V AC voltage correction 12V: If the transformer secondary symmetrical center tap, with full-wave rectification, then the secondary voltage can also be set lower, 11.5V ~ 12V can be.

Q:What is a linear regulated power supply: According to the adjustment of the working state of the tube, we often put the power supply is divided into two categories: linear power supply and switching power supply. In addition, there is a small power supply using a regulator.

Q:My graduation thesis needs, as long as 40 words is enough!: With the rapid development of today's society, the application of electronic systems is becoming more and more extensive. Electronic equipment has become an indispensable part of people's daily work and life. As the heart of electronic equipment  power system to the electronic equipment to provide the necessary energy  plays a vital role. Power system Good security and reliability is an important guarantee for the normal operation of electronic equipment.

Q:DC power supply production: 1, DC power supply installation (1) preparation before installation ① check the quality of the printed circuit board; ② all components must be tested before installation; ③ handle the soldering iron to do the preparation of welding. (2) the detection of components First control the principle of circuit diagram, read the printed circuit diagram. The components of the circuit diagram and physical components for comparison, understanding of physical components. And then the components to detect. ① control the principle of the circuit, list the components list. Draw a list of components. ② check the test resistance, capacitance parameters. Test the Capacitance of Small Capacitors with a Digital Multimeter. There are no special requirements for resistors and capacitors in this circuit. ③ check the potentiometer is intact.

Q:Power supply 4.5v can drive 3.6v lithium battery: it is recommended: 1, carefully measure the output voltage of the regulated power supply. 2, if it is 4.5 volts, easy to transform the output can be connected to a "germanium diode" (its forward conduction voltage is 0.2 ~ 0.3V), will make the output voltage is basically reduced to the appropriate.

Q:Regulated power supply and load configuration: 3, the output power of the power supply products are generally measured in pure resistive load, and pure resistive load, linear load, non-linear load of the internal power factor is not the same, very different. Pure resistance type load power factor of 1; linear load power factor is generally 0.6-0.8, non-linear load power factor is generally seen as 0.2-0.4. So the power of the same power supply products can match the load of different nature of the maximum power is not the same. 4, the non-linear load power in the calculation need to be multiplied by 5 to charge the power supply load power, the linear load power in the calculation need to multiply by 1.5.

Q:What is the regulated power supply?: That is, through the rectifier, filter to provide the required stable voltage power supply device

Q:How to control the DC regulated power supply output current constant? Such as constant output around 2a: Power supply can not do, you need is a constant current source.

Q:AC power supply and DC power supply difference: AC power supply and DC power supply difference is: AC power supply is stable AC power, DC power supply is stable DC

Q:Why is the DC regulated power supply connected to the load circuit after the voltage is reduced: 1, the access load exceeds the actual power supply capacity of the power supply; 2, the power supply design problems: drive the drive force is insufficient, the base injection current is too small, the capacitor capacity is too small, etc.: 3, circuit parts have problems, resistance deterioration, transistor aging, etc.: 4, the AC power supply voltage is too low, AC low voltage side voltage is lower than the required voltage, etc.: 5, the transformer power is too low - inadequate.
