Q:Switching power supply
A voltage is converted to another voltage, the crude pressure is converted to fine pressure
Q:What is the relationship between the input power of the switching power supply and the primary side of the switching transformer?
In the input voltage must be certain, the switching frequency of a certain situation, the smaller the input power, switching transformer primary side of the inductance but the greater the general, if the input voltage, switching frequency uncertainty, there is no comparable. On the forward power and counterattack power, the meaning of some different. The purpose of the counterattack is to allow the transformer to store the appropriate energy when the switch is turned on because the counterattack power supply does not output energy to the load during the turn-on of the switch and is only stored by the transformer during the switch Energy on the load output power, inductance is small, the excitation current is large, energy storage on more. On the forward, the purpose is to reduce the no-load energy consumption, because the forward power is in the switch tube conduction time to the load output power, do not rely on excitation energy storage. Transformer primary side of the volume of the transformer with the volume of the transformer is not necessarily related to the number of turns by the coil, the transformer is based on the power required to select the power, usually see the situation is the power of the smaller power supply, transformer volume small.
Q:Switching power supply, 2SC3320 switch tube is always burned
In general, the main reasons for the damage to the power switch tube are the following 13:        1. Soft start circuit failure        2. Switch tube integrated circuit board anti - peak absorption circuit failure        3. Positive feedback is too strong        4. Timing capacitor failure leakage        5. Decoupling Capacitor Failure in Regulating Circuit        6. The negative feedback loop of the regulator circuit
Q:What is the open-frame switching power supply?
Switching power supply of the actual, 24V, etc.), if the PC power is generally a metal shell, with a semiconductor power device as a switch, input AC220V, Through the high-frequency transformer coupled to the secondary, is the high-frequency transformer. AC220V switching power supply refers to the input is AC220 volts, a power mode into another form of the main circuit called the switch converter circuit; change with automatic control closed-loop stable output and protection is called switching power supply. But also at any time to check the current power supply equipment, generally from the insulation effect. Through the switch tube and shock circuit, such as electronic rectifier with the 13001--13007 series, the basic principle of switching power supply is: the 220v 50HZ exchange,
Q:How to make the switching power supply does not delay power
Use a relay to control the output of the switching power supply.
Q:12V switching power supply, which brands through 3C certification?
3C certification is China's mandatory product certification, where the directory in the 3C certification required to be certified products need to be certified to the factory sales, import and use in business activities. The PC power supply belongs to the directory to be mandatory certification of products, so in the market of formal power products will be mandatory through the 3 C Such as HuntKey, Colorful, Great Wall, GOLDENFIELD, TT and Cool Cold's mainland sales products.
Q:Will a 12V10A switching power supply with a few 12V2A surveillance camera?
You can take 5 no problem, depending on the quality of the power cord to see you generally 1.0 of 200 meters no problem.
Q:What is the meaning of hiccups in switching power supplies?
Hiccups that the switching power supply in the output short circuit and other failures, the switching power supply chip after working hundreds of milliseconds and then stop working for a few seconds, and then start working hundreds of milliseconds, continuous cycle.
Q:What is offline LED driver? Offline switching power supply
Off-line switching power supply, also known as isolated switching power supply, is an AC-DC converter circuit. AC and DC are isolated by transformer. In some laboratories or high demand occasions, for the safety of the experimental staff, the experimental input power is generally used 1: 1 frequency transformer and the mains to isolate, so that the laboratory laboratory personnel regardless of which line encountered The root line will not have the risk of electric shock, because the isolated power and the earth is not connected. In industrial control equipment, it is sometimes necessary to isolate the power supply lines between the two systems, such as isolating ground noise, isolating high common mode voltages, etc., using a DC converter with a transformer to separate the two power supplies They are independent of each other, in order to achieve the above purpose. Each module is powered separately to prevent a module from damaging other modules due to high voltage discharge or other causes. The purpose of this can be to ensure that each module is working independently and undisturbed.
Q:What is the PWM high-frequency switching power supply
PWM is pulse width modulation As mentioned above, through the high-frequency switch output a pulsating DC, the filter output stable DC If the load changes will lead to changes in the output voltage then the system will adjust the output pulsating DC duty cycle to achieve the purpose of regulation. Upstairs that is the working principle of PWM-type inverter. What I'm talking about is switching power supply. Is actually a principle.
