- Q:Buy switching power supply should pay attention to what
- Their own parameters, the normal voltage accuracy, ripple, input range, current regulation, voltage regulation, insulation and so on. You can also consult the switch tube frequency, appearance, warranty time
- Q:Switching power supply circuit will ring what will happen
- Switching the power supply circuit to open the ring will make the output voltage instability. Switching power supply is to use the duty cycle of the adjustment switch to achieve a stable output voltage. When the load is increased or the input voltage decreases, the output voltage will be reduced accordingly, in the closed loop conditions, the switching power supply will automatically increase the duty cycle of the switch, the output voltage back to the original voltage. On the contrary, when the load is reduced or the input voltage rises, the output voltage will rise accordingly. Under closed loop conditions, the switching power supply will automatically reduce the duty cycle of the switch and return the output voltage to the original voltage. If the open loop, the switching power supply duty cycle is constant, then the output voltage will change with the load or input voltage changes, all the role of regulation.
- Q:12V switching power supply, which brands through 3C certification?
- Now basically is not the cottage products are 3C certification it They are not allowed to recommend or choose the manufacturers of products are generally more insurance Canada is the Great Wall is very good
- Q:Who can help me choose a switch power supply model 220V AC / 10V DC
- This type of power Taobao is more than, as long as the input (power 10V DC) can be.
- Q:I do 12V2A switching power supply when the 2A load, under normal circumstances work is normal. But is the beginning of the load that moment, when adding more than 1.3A, the output voltage dropped first low and then quickly returned to normal, what reason? This is of course not normal, the same load, for someone else's power but not the problem. How should we solve this problem? Just test a phenomenon is that when the sudden removal of the load when the voltage is also the first drop and then return to normal state. How to solve it?
- Before the load, the current is not large, switch on and off time ratio is to meet the capacitor charge, discharge balance, to maintain the output voltage unchanged. When the load is connected, the load is mainly from the capacitor, the capacitor discharge quickly, the voltage drop is very low, the switch has not adjusted conduction and turn-off time than the capacitance of the charge and discharge balance, this adjustment is gradually It takes time. So the output voltage, that is, the voltage on the capacitor, the first rise after the rise.
- Q:Switching power input is marked with 220V AC, 36V output, but the actual input voltage is 238V, the output of the switching power supply affect it? Will it damage the switching power supply? Do not know the reason is not the voltage, power after a period of time (10 minutes), the switch power suddenly no output, and the display is not bright, switching power is not already broken? Guiqiu prawn to the doubts!
- Switching power supply without output, usually two problems, the first is the switching power supply is broken, the second is the switching power supply output overload, power overcurrent protection or overheating protection, the former need to repair, the latter to remove the load off 220V input Voltage after 5 minutes and then on the 220V to return to normal. The input voltage of 238V is also within the allowable range of the switching power supply, regardless of this.
- Q:Direction switching power supply
- Switching power supply applications in the power electronic devices are mainly diodes, IGBTs and MOSFETs, transformers. SCR in the switching power supply input rectifier circuit and a soft start circuit in a small amount of application, GTR drive difficult, low switching frequency, and gradually replaced by IGBT and MOSFET. Switching power supply development direction is high frequency, high reliability, low consumption, low noise, anti-interference and modular. As the switching power supply light, small, thin key technology is high frequency, so the major foreign switching power supply manufacturers are committed to simultaneously develop new and highly intelligent components, in particular, to improve the secondary rectifier device loss, and power iron Oxygen material on the scientific and technological innovation to improve the high frequency and large magnetic flux density (Bs) to obtain high magnetic properties, and the miniaturization of the capacitor is also a key technology. The application of SMT technology makes the switching power supply has made great progress in the circuit board on both sides of the layout components to ensure that the switching power supply light, small, thin. Switching power supply on the high frequency of traditional PWM switching technology must be innovative, to achieve ZVS, ZCS soft switching technology has become the mainstream switching power supply technology, and significantly improve the efficiency of switching power supply. For high reliability indicators, the US switching power supply manufacturers by reducing the operating current, reduce the junction temperature and other measures to reduce the stress of the device, making the product greatly improved reliability.
- Q:12V10A switching power supply in the layout of the line when the longest cloth?
- Power power: 12X10 = 120W; Monitor the camera power: 12X2 = 24W; Current point of view: 10A divided by 2A = 5; Power point of view: 120W divided by 24W = 5; So you can install five (the same voltage, the current and power which is less, with that standard).
- Q:How to choose the switching power supply frequency?
- such as 300KHZ better magnetic material can do 500KHZ or more high. Input voltage and then higher, we need to pay attention to the switch tube switching loss problems, and generally only to do dozens to hundreds of hundreds of KHZ or so. The specific circumstances of the specific analysis, and some soft-switching, resonant what the high-power high-efficiency topology!
- Q:What is the difference between Switch Mode Power Supply and electronic switch? Where are they?
- To the electronic switch to open a signal, the line connected, disconnect the control signal or to a shutdown signal, the electronic switch off. The electronic switch differs from the normal switch in that it is non-contact. So to avoid such as manual switch button and contactor lights in the opening and breaking when the spark loss and mechanical noise. And control the power of small control easy. Switching devices in the switching power supply, such as MOS tube and IGBT are all electronic switches, SCR also belong to the electronic switch. And we usually mention the electronic switch is the market of solid-state relays, etc., it is also the principle of the use of thyristor.
