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:Is it possible to power the regulator and the regulator? Please enlighten me
The general sense of the power supply and regulator is one thing.
Q:BEC (UBEC) and adjustable buck regulator power supply is different
Point is the line is simple, small size, as long as a regulator can be, but the disadvantage is the conversion efficiency is not high, when the energy regulator Loss of large (linear regulator efficiency is generally only 65% -70%), so in the course of the regulator will be very hot tube (electric transfer hot

Q:Strange op amps and trips made of adjustable regulated power supplies, how does it work and where is it?
I was the first time I saw this structure, I understand this: LM338 - 5.0 is a precision 5V voltage reference, the dynamic internal resistance is very low, the typical value is 0.6Ω, op amp LM308 is the emitter follower connection, 2,3,6 feet equal, that is, V2 = V3 = V6 = 5V, Rs and triodes constitute a parallel regulator circuit, and the op amp is the controller. Vin ↑, V3 ↑, V6 ↑, Io ↑ (op amp output current), I7 ↑ (op amp supply current), Ie ↑, URs ↑, Uout ↓.
Q:Adjustable AC power supply is the variable frequency power supply?
Your output frequency is not 50HZ, with variable frequency power supply, if the output frequency is 50HZ, with the regulator can be, the general election 1KVA can, the price of hundreds of good,
Q:DC power supply is generally composed of several parts
It can be in the grid voltage and load current changes, to maintain the output DC voltage stability. It is an important part of DC power supply, DC power supply determines the important performance indicators.
Q:How to control the DC regulated power supply output current constant?
Constant current produces a constant electric field, but also a constant magnetic field, but the constant electric field and the constant magnetic field field is independent of each other. Due to the role of constant electric field, the free charge in the conductor to increase the rate of movement; and the process of movement with the conductor The internal stationary particles collide to decelerate, so that the average rate of free charge does not change with time. Constant current concept: the size of the direction of the current does not change the time. Suzhou Greenspan Power is a Sino-US joint venture, long-term based on the cause of industrial power, is set product development, production and sales as one of the high-tech enterprises. The main products are frequency conversion power supply, IF power supply, AC constant current source, DC power supply, UPS, high precision power supply and photovoltaic inverter power supply and other products
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.
Q:Design DC power supply,
Directly to buy a test of the power supply, but also their own design plate, trouble
