- Q: Can notebooks have an external switching power supply?
- Yes, you need to have a certain maintenance experience of the maintenance staff to get, the following details of the production process First note that the notebook hardware at the hard disk, memory, cpu, the other specifications are different. Therefore, the notebook key to open several, contact type, cable type, there are fixed, and so on it, a variety of. In the case of contact, for example, other basic ideas are the same. The first step, open the computer after the shell, remove the motherboard. The second step, find the laptop key position (on the motherboard position), usually in the computer's switch key (start the computer button) near the location.
- Q: What is the PWM high-frequency switching power supply
- PWM-type high-frequency switching power supply is the use of pulse width modulation (PWM), referred to as pulse width modulation, is the use of microprocessor digital output to control the analog circuit is a very effective technology, widely used in measurement, communication Power control and transformation in many areas of power. PWM switch regulator or steady current power supply basic working principle is in the input voltage changes, internal parameters change, external load changes in the case, the control circuit through the control signal and the difference between the reference signal closed-loop feedback, adjust the main circuit switching device Of the conduction pulse width, making the switching power supply output voltage or current control signal is stable.
- 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: What is the output of this group? If the power supply to the 48V, is not +24 V termination of the electrical 48V + input, -24V termination of the electrical 0? is this okay? Voltage difference is 48V ah? Thank you very much!
- 24V and -24 V voltage difference is 48V, then it is the same power can be used when the 48V power supply to pay attention to electrical power A simple description of the source of the 24, with two batteries in series with the negative side of the voltmeter connected to the midpoint of the series, the positive measurement of the two ends of the battery, you get a positive 1.5V and a negative 1.5V voltage
- Q: What is the use of transformer shielded grounding in switching power supply?
- Internal shielding: between the primary side and the secondary side to increase the winding or copper foil, leads to one end of the original side of the work above the main purpose is to the primary side of the common mode interference signal through the shield back to the source of harassment, if not the shield Layer, there is a common mode interference signal will be passed between the primary winding between the interlayer capacitance to the secondary side, causing the output of the EMI problem. External shielding: in the transformer outside the magnetic core and winding coated with a layer of copper foil, this layer of copper foil to be closed to form a ring circuit. The leakage magnetic field of the transformer is not closed inside the core, but leaks into the external space. In the high frequency application, the strong leakage magnetic field will induce the voltage in the closed loop of the input and output ports, resulting in EMI test results deteriorate. If there is an external shielding layer, according to the principle of electromagnetic induction, the shield layer will induce the current, the formation of the opposite magnetic field, offset the transformer leakage magnetic field effects.
- Q: What is the linearity of switching power supply
- Linear adjustment rate for the input voltage maximum and minimum output voltage stability indicators, but this provision has a number of standards to 220V, for example, if you specify a maximum of 264, the minimum is 185V, Vof said full load when the output voltage, there are three algorithms : The algorithm is as follows: ??? ATE which in the end with which one, you will test the report out to count about. I used to use the CHROMA6000, which is the formula inside the dead, but CHROMA8000 as if you can modify their own. For only a set of outputs, there is a LOAD REGULATION is the load regulation rate, Von said no load when the output voltage, the algorithm is as follows: ???? Respectively, called the normal voltage load regulation, high pressure load regulation, low voltage load regulation. When there are multiple sets of output, one or more of the output with overloaded but no load output increases due to the increase in duty cycle, relative to the original increase in the number of cross-load regulation is called Accuracy range, because each group must be set at least once overload or light load to observe the other output of the situation, so called cross adjustment.
- Q: What is the difference between non-isolated flyback switching power supplies and isolated switched-mode power supplies.
- There is no transformer in the non-isolated circuit. The so-called forward and the flyback is very good, the flyback transformer has energy storage, transformer primary and secondary with the same name on the contrary, drive signal conduction, primary conduction, secondary cut-off, energy storage; drive signal cut-off, primary Cut off, secondary conduction, pass. While the forward transformer is no energy storage, and the primary and secondary are in phase
- Q: Switching power supply OLP and OCP these two are the same concept?
- OCP is overcurrent protection, many electronic devices have a rated current, not allowed to exceed the rated current.
- Q: What is switching converter and switching power supply?
- Switching power supply is 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 generally by the pulse width modulation (PWM) control IC and MOSFET composition. Switching power and linear power compared to the cost of both the output power increases with the growth, but the growth rate of the two different. Linear power costs at an output power point, but higher than the switching power supply, which is called the cost of reversal point.
- Q: Switching power supply, Fairchild Semiconductor's switching power supply chip data, the application of the chip design switching power supply can be divided into two categories: Adapter and Open Frame, and the general application of the former Adapter mode design power than the latter will be large The What kind of structure or type, what is the difference between the two?
- Adapter has a closed shell, openframe no shell, the former heat dissipation is relatively poor.
