Q:Switch DC power supply is what it means
Commonly speaking, switching power supply is AC rectifier filter, and then through the crystal switch and a certain voltage regulator circuit, the switching transformer output high frequency voltage and current, rectified filter output stable DC power supply. "Best answer"
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: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:Use 7812 to make a positive 12V DC power supply
1st floor ny_peter circuit diagram is basically correct, but the transformer secondary voltage setting is too high, which will make the power efficiency is low, in the larger output current regulator serious heat.
Q:Adjustable DC regulated power supply works
The working principle, application and prospect of the voltage source. First, the working principle of DC power supply DC power supply is a 220V frequency AC power conversion voltage regulator output voltage of the device, it needs to go through the transformer, rectifier, filter, regulator four links to complete. The working principle of the four links is as follows: (1) Power transformer: is a step-down transformer, it will convert 220V AC voltage to meet the required AC voltage, and sent to the rectifier circuit, the transformer by the secondary side of the transformer voltage The (2) rectifier filter circuit: rectifier circuit converts the AC voltage Ui into pulsating DC voltage. And then filter the filter circuit to filter out the larger ripple components, the output ripple smaller DC voltage U1. Commonly used rectifier filter circuit with full-wave rectifier filter, bridge rectifier filter.
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:What is the working principle of an adjustable DC regulated power supply?
Rectifier and filter circuit works, characteristics and calculation of the main parameters. 1 silicon voltage regulator diode regulator circuit 1 Zener diode characteristics The use of silicon diode reverse breakdown characteristics, can produce a zener diode. The general diode is not allowed to work in the reverse breakdown area, because the reverse current IR is large, the breakdown power consumption P = IR ?? UBR is very large, beyond the maximum allowable diode power loss, the diode Will be burned. Zener diode junction area of the larger, allowing greater power consumption, as long as the breakdown power consumption does not exceed the allowable value, the Zener diode will not burn. For example, there is a Zener diode power consumption PZ = 500mW, reverse breakdown voltage UBR = UZ = 10V, then the maximum reverse current
Q:What is AC regulated power supply
AC power supply and DC power supply difference is: AC power supply is stable AC power, DC power supply is stable DC
Q:In the use and installation of the regulator, what should be noted
Second, the security matters ⒈ power supply in the power supply start, do not arbitrarily open the regulator power supply or pull the power supply input and output connections to prevent electric shock or other electrical safety accidents. ⒉ power supply input and output power supply must be arranged reasonable to prevent trampling worn, resulting in leakage accident. ⒊ power supply must be reliable grounding, due to non-ground wire operation caused by electric shock or human injury, by the user responsible for their own. ⒋ power supply can not be connected to the power line in the heating pipes, water pipes, gas pipelines and other public facilities, so as not to infringe the rights of third parties or cause harm. ⒌ should regularly check the power supply input and output connection, so as to avoid loose or fall off, thus affecting the normal use of power supply and safe power. ⒍ voltage regulator cable matching must meet the provisions of the current capacity to carry enough capacity of the cable. ⒎. Regulator should be gently, in the work of time to avoid severe vibration; ⒏, to ensure that the regulator of the carbon brush spring has enough pressure to avoid the carbon brush and coil contact surface flash; ⒐, non-professionals please do not open the regulator power supply or power supply for maintenance.
Q:BEC (UBEC) and adjustable buck regulator power supply is different
BEC full name is battey elimin In the electric circuit set up a circuit module, the 12V battery output voltage turn Switch to 5V-6V to the receiver and steering gear and other electronic equipment (of course, the motor or 12V power supply) This eliminates the need for that 5 V battery This is the origin of the BEC (battery-free circuit) name. BEC mostly use linear regulator, linear regulator of the excellent way
