Q: Do you need to consider the power to choose a regulated power supply?: Be sure to consider the power, if the load required power is greater than the power supply, the power will be damaged. Power output power can be roughly estimated, the estimated method: the maximum output power of the power supply = output voltage x maximum output current Rated output power of the power supply = output voltage x rated output current

Q: Material: 3.7V, 5V DC power supply, the general number of two transistor, any resistance to a number of resistance, require 1.2V DC voltage, and power requirements as large as possible. LM317, LM385 this thing is good, but the hands did not, do not want to run this trip because of this thing to buy. The The Can I use multiple diodes in series to get 1.2V? Does this offer high power? Or is there any other good advice? Hope that the circuit design as simple as possible, I hope we can help.: Ordinary transistor is not high power. Is like LM317 so big or bigger than him? If this is the case. Very good to do. How much power to how much power. See figure. Haha. How much input voltage can be But if the difference between the output and the input is too big, it will heat up. This figure is based on the principle of diode voltage drop of 0.7V. You can measure the output voltage. According to the need to add and subtract transistor B pole of the diode ... ...

Q: Adjustable DC regulated power supply works: (3) filter circuit: the rectifier circuit output voltage in the majority of the AC component to be filtered, resulting in a relatively smooth DC voltage of the filter capacitor C to meet RL-C = (3 ~ 5) T / 2, or T For the input AC signal period, RL is the equivalent load resistance of the rectifier filter circuit. (4) voltage regulator circuit: the function of the regulator circuit is to stabilize the output DC voltage, does not change with the AC grid voltage and load changes. Commonly used integrated voltage regulator has a fixed three-terminal regulator and adjustable three-terminal regulator. Commonly adjustable adjustable positive pressure regulator with CW317 (LM317) series, their output voltage from 1.25V-37V adjustable, the simplest circuit external components only a fixed resistor and a potentiometer. The chip has a transition, overheating and safe working area protection, the maximum output current of 1.5A. The output voltage Uo expression: Uo = 1.25 (1 + R2 / R1) where R1 generally take 120-240 ohms, the output and the adjustment of the end of the output voltage regulator, the output voltage Uo of the expression: Uo = 1.25 (1 + R2 / R1) The differential pressure is the reference voltage of the regulator (typically 1.25V). I uploaded the principle of switching power supply and write the above design.

Q: Is it possible to power the regulator and the regulator? Please enlighten me: Regulated power supply and regulator is one thing, the regulator output is the power supply. ???????The stabilized voltage supply is an electronic device that provides stable AC power or DC power for the load. Including AC power supply and DC power supply two categories. ??????Voltage stabilizer (English: voltage stabilizer) refers to a kind of electronic engineering is designed to automatically maintain a constant voltage device. A regulator may be a simple "feedforward" design or may contain a negative feedback control loop. The regulator may also use an electromechanical mechanism or an electronic module. According to the different design, the regulator can be divided into DC regulator and AC voltage regulator. Regulators are often used in power supply systems and work with rectifiers, electronic filters, etc. to provide stable output voltages, such as the operating voltage required for microprocessors and other components. In the generators and even large generators in power plants, regulators control the stability of the output voltage. In a distributed distribution system, the regulator may be installed in a substation or along the direction of the wire extension to ensure that the user regardless of the power level can be a stable voltage.

Q: Why study DC power supply circuit: As for why the acceptance of DC power supply circuit, is certainly to do DC power supply.

Q: In the experiment, which two ways to obtain DC power supply: With the transformer step-down, after rectification filter, regulator to obtain adjustable power supply

Q: How to choose a regulated power supply: Buy the power supply is the most important thing to figure out how much load power, load nature is what. General non-inductive load in accordance with 1.2-1.5 times to match, that is 10KW equipment with 12-15KVA on it. Inductive load in accordance with 2-3 times to match! If the response time, the waveform has special requirements on the need to use precision purification regulator or non-contact regulator

Q: DC power supply through what way to achieve the purpose of regulation: DC power supply is generally divided into two categories, one is linear regulator, the common is to use a three-tube voltage regulator tube, by changing the transistor base voltage to adjust the output voltage to achieve the regulator output Purpose, generally used in low-voltage regulator circuit, the transistor work loss is great, relatively serious heat, generally need a larger heat sink, due to the transistor limit, the output circuit is generally less than 5A, greater than the current need to adjust the tube in parallel.

Q: Who bought a computer, but in the case of uninterrupted power is always automatically shut down, and later heard that my family away from the transformer far, voltage instability, then I bought a regulator, but the effect is not very good, There is still a power outage, and some people say that to buy a power supply, I do not understand the function between the two and the difference, please master answer!: Adjust the power supply regulator than the amplitude of the regulator, adjust the voltage width than the width of the regulator, for example, the regulator can only be 200V voltage transferred to 220V, but the regulator can be 180V Voltage transferred to 220V, so the power supply is better, but relatively high prices. Or do not buy, too expensive, the family is not necessary, because after the power, can only be maintained for about 15 minutes, their own use, and no important things, afraid of a sudden power out of something important to save, UPS is a must Do not spend that money

Q: Is there a difference between a regulated power supply and a power adapter?: The first is the role of voltage regulator voltage is the second transformer power supply equipment
