Q: From the old computer to remove a switch power supply can do what, can be used when the power? how to use?: Yes, the main power is enough power. Voltage and current are appropriate.

Q: There are positive, GND and negative, GND and negative connected together.: 1, the power supply is the two output terminals to negative as a reference, you can think it is a positive power supply, with positive as a reference, it can be considered a negative power supply. 2, DC power supply refers to the ambient temperature, load size, input voltage and other factors will make the DC voltage regulator output voltage changes in the power supply. 3, the power supply of the classification of many methods, according to the type of output power supply DC power supply and AC power supply; according to the regulator circuit and the load connection is divided into series power supply and parallel power supply; The working status of the tube is divided into linear power supply and switching power supply. According to the circuit type, there are simple power supply and feedback type power supply. So many of the classification is often so that beginners puzzled, do not know where to start. In fact, it should be said that these seemingly a lot of classification between the methods have a certain level of relationship, as long as the level of this level can naturally distinguish the type of power.

Q: Members help me to explain the role of the various components in detail. The There D5 regulator is 21V why the output is 20V, they said to reduce the UBE0.7V pressure drop. I do not understand, why should subtract UBE ah? The more detailed the higher probability of adoption. The Remember the details. The The Thank you all the teachers. The ? Mainly three-tier tube is how to complete the regulator?: First, you have to know that the VT working state is in a magnified state or a saturated state, so VT's Ube> 0. VT is in magnified state, Ube = 0.7v. D5 to ground voltage (ie VT base voltage) = VT Ube + circuit output voltage Uout Uout = Ud5-Ube = 21v-0.7v

Q: The circuit teacher said the capacitor can not be 10uf, should not the same! Specifically did not say, ask the big god say, the specific capacitor should be how much ah! Check a lot, not found! Thank you!: This is nothing to calculate, are experience only. In addition the other two capacitors on the right is generally a electrolytic capacitor (large capacity) +1 non-polar capacitor (small capacity), to improve the high-frequency power output characteristics

Q: What should I pay attention to when using a function signal generator and a DC regulated power supply?: When using the function signal generator, pay attention to the output signal from small to large, slow adjustment

Q: DC power supply through what way to achieve the purpose of regulation: The other is a switching power supply, generally isolated and not isolated, they use a variety of voltage regulator, the common output voltage is sampled through the feedback circuit to control the pulse width of the switch to stabilize (PWM), there are Special way of using FM (resonant).

Q: Why Capacitor Filtering in DC Regulated Power Supply: Rectified DC is pulsating! The high charge and low charge characteristics of the capacitor can make the pulsating current become smooth DC!

Q: Can you use the adjustable DC regulated power supply at home to wind the sail 12V 54Ah 265A battery charge: Battery capacity is large, adjustable power supply maximum output current is how much? If you can reach 5-6A, 16 hours or so can be filled. If the current of 1A, do not rush. If you need to always charge at home, it is recommended to buy 12V, 100W switching power supply. Fine-tuning function (transferred to 13.8V), you can series a small resistance (zero a few ohms) current limiting charge.

Q: Electrical Engineering! Why can not directly use a multimeter to measure the power supply of the exchange of ripple?: In general, multimeter AC can only measure the pure AC voltage. The output voltage of the regulated power supply is equivalent to the DC voltage + ripple voltage, and the multimeter exchange file can not be measured normally. In addition, the ripple voltage is not necessarily a sine wave voltage, the regulated power supply itself or by external interference will produce complex ripple voltage, and the general multimeter AC voltage file is measured the average AC voltage. The ripple voltage is not a pure sine wave when the multimeter can not be accurately measured. From the other side, the general linear power supply can only guarantee the output voltage in the lower frequency range of stability, and for more than tens of kHz ripple rejection is very limited. That is, the ripple voltage frequency is generally higher, may have exceeded the multimeter AC file frequency response range, this time the multimeter is still unable to correctly measure.

Q: What is the DC power supply load characteristics of the curve, how to determine, good and bad What is the performance, if not good, how to improve it, please advise people: DC load power supply load curve, that is, the relationship between the output voltage and load resistance curve (the greater the resistance the higher the output voltage), is determined by the output power of the power supply itself. On the improvement that depends on what you do the circuit, and now the more popular is the switching power supply, is to control the duty cycle, the first output square wave, and then after the filter circuit. If you want to have a voltage regulator circuit, the feedback circuit is based on the load to adjust the power duty cycle. An electronic device that provides stable DC power for the load is called a DC regulated power supply. DC load power supply load curve, that is, the relationship between the output voltage and load resistance curve. Load (resistance value) The smaller the power, the output voltage is relatively stable, the load (resistance value is small) the greater the power, the lower the output voltage).
