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: Hello! I would like to ask you a question! My computer in a sudden loss of power after a home, then I want to go home with a voltage regulator, standby power function of the machine, the market there is no such machine, where installed can protect all the electrical appliances at home? Thanks: Hello there! You said the function requires two machines to complete: 1, the regulator: the external network input voltage is stable at the standard mains voltage of about 220V device. Installed in your home meter behind you can protect all the appliances. Power grid voltage is too high, beyond the upper limit of household appliances design, household appliances can not withstand the high voltage and the possibility of damage. The grid voltage is too low, the starting current of the electrical appliances will be low starting voltage, start the current is small and can not start normally, serious may make it long in the start of the high current state and damage the core components. 2, uninterruptible power supply (UPS): is to give your appliances to provide an uninterrupted power supply, such as power failure when your computer is not a power outage to eliminate the illegal shutdown caused by unnecessary losses. Due to power constraints, can not receive high-power appliances, in fact, no need to pick up other electrical appliances, only connected to the computer just fine.

Q: When the power supply is used, pay attention to what: 5. The output voltage step selector should be placed in the proper position as required before starting. 6. In the loading process does not allow the conversion step selector switch gear, if you want to change the gear to be removed after the load to convert. Like Shanghai Zhengxi regulator of the security is better. "

Q: Need a circuit, marked the size of the components, it is best to have a detailed calculation process. The circuit diagram can be viewed under MULTISIM Or send something to my mailbox Do good cash reward: In this figure the adjustable R2 ground terminal access 1.25V negative voltage on the line friends. The The The The The The Other filter capacitor, then appropriate to adjust it

Q: The difference between the series DC power supply and the parallel DC power supply: The main difference: parallel DC power supply / low efficiency, especially when light load, the power is almost all consumed in the current limiting resistor and adjust the tube; * Output voltage adjustment range is very small; stability is not easy to do very high. The series power supply is just to avoid these shortcomings, so now widely used are generally series power supply.

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: How to choose a regulated power supply: First you use the power supply to determine the load, such as you want to access the load voltage is 12V, the load current is 4.3A, then you choose to power supply, we must choose 12V / 5A power supply.

Q: DC power supply design and production of what materials: The simplest constant voltage DC power supply requires the following materials: 1, transformer 2, rectifier diodes or bridge heap 3, filter with electrolytic capacitors 4, the regulator circuit (78 series of fixed three-terminal or adjustable three-terminal regulator LM318, LM338) 5, other needs of electronic components (resistors, light-emitting diodes, potentiometers, etc.).

Q: How the DC regulated power supply outputs a negative voltage: 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.

Q: Switch DC power supply is what it means: Should be a "DC switching power supply," refers to a voltage conversion power supply circuit, the main component is a transformer and a "open and close" function of the transistor, transformers and transistors in series in the circuit, the DC through the transistor " Open and close "state to form a pulse voltage on the circuit, the pulse voltage in the transformer core to form an instantaneous change in the magnetic field, and then in the same magnetic field on another coil to induce the pulse voltage, the pulse voltage through the rectifier And the filter is the output of the DC voltage, the regulator part of the output voltage is provided by the signal control transistor on and off the time and amplitude, to achieve the purpose of regulation, a few words can not tell, interested in the power network to see it, Where a lot of master
