Q: I have a 12V3A switching power supply. From 0V to 12V, 2V3V can start. Want to carry out voltage regulation. How to do? If you use the potentiometer to connect the kind of potentiometer. I connected to the permanent magnet three brush motor is the car with the wiper motor, the motor high and low speed adjustment. Originally wiper motor there are two blocks. Richer speed adjustment.: Ordinary single-bit potentiometer If your switching power supply itself is with the regulator then the board should have a voltage regulator potentiometer that removed in a resistance and the same as the original can be a motor when the two can only use a block Fast on it

Q: What is the difference between what we usually call switching power and ups?: Switching power supply is a simple power supply, and the transformer power supply name difference. High efficiency and stable operation Wide voltage range. UPS on the complex it includes switching power supply function is different from the power supply. It consists of step-down circuit boost circuit charging circuit detection circuit and battery. It is widely used in emergency power systems, protection of computer information, security for the security system. Remember the crash in Wenzhou? Power failure caused by automatic monitoring paralyzed, and this time on the use of the UPS.

Q: What is the flashing time in the switching power supply?: Blanking time intuitively speaking, in this period of time the controller does not move. For example, IC current detection pin, whenever the power MOSFET to open a current sense resistor is not inevitable to produce a peak voltage.

Q: What is a linear adapter and a switching power adapter: . Linear power supply efficiency is low, and switching power supply efficiency is higher. But the linear power supply EMI is low, and the switching power supply EMI is higher, especially the low power. So the use of different!

Q: 24v switching power supply can do car battery charger?: 24v switching power supply can do car battery charger, but also need to limit the charging current measures, do not know that the switching power supply can output the current is enough, too small, the charging time will be very long.

Q: What is the difference between non-isolated flyback switching power supplies and isolated switched-mode power supplies.: This question can be divided into several phrases to distinguish: Non-isolated: The power input and output are electrically connected. As shown below: Turn left to turn right Turn left to turn right Isolated: The power input and output are independent of each other in the electrical structure and are connected only by transformers (magnetically coupled) and optocoupler (optocoupler) devices. Forward-pulse transformer phase / edge relationship, to ensure that the switch tube conduction, drive the primary transformer pulse transformer, while the transformer side of the load power supply. Turn left to turn right Flyback type: flyback circuit and the forward circuit is the opposite, the original transformer transformer / phase relationship, to ensure that when the switch is turned on, driving the pulse transformer primary side, the transformer side does not load the power supply, that is, Side staggered off. Turn left to turn right Switching power supply: the use of modern power electronics technology to control the switch on and off the time ratio, to maintain a stable output voltage of a power supply, switching power supply is generally composed of pulse width modulation (PWM) control IC and MOSFET.

Q: Yesterday when the transformer to find a problem, a boost inductance, my air gap plus the greater the inductance of the smaller, but a counterattack transformer my air gap plus the more inductance but the greater, now a bit can not figure out.: The same winding the same diameter of the conditions, the greater the air gap, the smaller the amount of inductance. The larger the air gap, the lower the permeability, the smaller the inductance.

Q: What is switching converter and switching power supply?: Switching converter is a core component of modern energy conversion technology. It is also a basic component of all kinds of switching power supply, inverter, UPS, photovoltaic power generation, wind power generation and LED lighting. It is widely used in electric power, communication, home appliances, railway transportation , Automotive electronics, industrial control, instrumentation, aviation, aerospace, navigation and other fields.

Q: Switching power supply, constant current power supply, resistance to the power supply where the benefits?: Roughly compare it Switching power supply, RC power supply ----- these two, the general switching power supply to do greater power; resistance capacity of the power is generally micro power Constant current power supply and the above species is not compared, the switching power supply can also be done

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?: To increase the dynamic dynamic response speed of the power supply, it is necessary to increase the power supply bandwidth. With external feedback can adjust the feedback power supply bandwidth (bandwidth is easy to instability, to ensure stable power), or increase the output capacitor can also increase the power supply bandwidth.
