Q: Switching power supply COM how to connect: Originally is the ground ah, but the output of the ground is the output voltage is not the input of the ground can not be wrong ah multi-channel output power is some public

Q: Why the use of high-frequency switching power supply: Improve the switching frequency can improve efficiency, thereby reducing the size of the transformer, and then the entire power supply volume will come down There is, switch state, oscillation, then the frequency of <20KHZ ears can hear the noise, so from this point of view can not be less than 20K

Q: High power high frequency switching power supply with what rectifier: Input level with ordinary rectifier can be, the output stage recommended with silicon carbide diodes

Q: I copied a circuit board, 7W switching power supply, line and the original circuit is exactly the same, that is slightly different alignment, no power after the output. I made two boards, are the same ask, ask the master, where is the problem? How to deal with?: IC is generally the auxiliary power supply is a problem, the relevant components to check: R8, R9, Q3, Z1, D5, R14, and transformers. Finally, U2. The main thing you want to look at the voltage of the IC VCC pin is not within its specified range, if the IC problem, if not, from the C1 positive step by step to find over.

Q: What is the meaning of hiccups in switching power supplies?: Hiccups Hic cups When the power supply in the over-current, over-voltage and other abnormal working conditions: Module control circuit to monitor the module exception -> control system ordered shutdown -> For a period of time no output -> after the set the shutdown time system need to confirm whether the abnormal state is canceled at this time the module ordered boot Y abnormal state to eliminate the module follow-up normal work N abnormal state still exists return to the first step to continue the cycle If the exception has been the existence of the module will be over a period of time to boot and then quickly shut down this is the hiccup

Q: We use the switching power supply is 220v-48v, the room has air conditioning, air conditioning power in 6kw or so, the total power of this room in 17kw, DC current is 60A, the room has two tubes. Now do not know how much switching power supply losses, these devices may have 17kw power? This is the 17kw power meter on the show. Who heroes help me.: Need to know the switching power supply load current or load power and switching power supply efficiency. General switching power supply efficiency (220v-48v) is greater than 80%, 80% efficiency, its power consumption is equal to the load / 80%. Glossary: 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. With the power electronics technology development and innovation, making switching power supply technology is constantly innovating. At present, the switching power supply to small, lightweight and efficient features are widely used almost all of the electronic equipment, electronic information industry is the rapid development of an indispensable power supply. With the rapid development of power electronics technology, power electronic equipment and people's work and life increasingly close relationship, and electronic equipment are inseparable from the reliable power supply, into the 80's computer power to fully realize the switching power supply, the first to complete the computer Power supply, into the 90's switching power supply have entered a variety of electronic, electrical equipment, program-controlled switches, communications, electronic testing equipment, power supply, control equipment, power supplies have been widely used switching power supply, but also promote the rapid development of switching power supply technology

Q: I am now learning switching power supply, read some of the information in the "work in the CCM state of the flyback power", because of this do not understand, would like to ask the power of friends can give to explain, very grateful! As well as the principle of positive and reactive work mode? And tell me what I want to learn switching power supply only little knowledge of what I now learn from?: 1) on the switching power supply CCM and DCM state is the transformer magnetizing current, in fact, flyback switching power supply secondary side of the current working state there are three: Magnetically search the critical state of the current: At this time the primary shutdown power Toff = the ratio of the secondary inductor to the output voltage divided by the secondary peak current. The discontinuous state of the magnetized current DCM: Toff> The ratio of the secondary inductor to the output voltage is divided by the secondary peak current. Continuity of magnetization current CCM: Toff ≤ The ratio of the secondary inductor to the output voltage is divided by the secondary peak current. 2) forward and flyback power mode principle Single-ended flyback is the primary MOS turn-on when the secondary diode is turned off and the forward is synchronized. 3) Want to learn about switching power supply first learn electrician electrical and magnetic look at power supply network.

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: Working principle of small switching power supply: Switching power supply is used to control the switch through the circuit for high-speed pass and cut off. The conversion of direct current into high-frequency alternating current is provided to the transformer for transformer, resulting in the required group or groups of voltages! The reason for the high frequency AC is that the high frequency AC is much more efficient than the 50HZ in the transformer transformer circuit. So the switch transformer can be done very small, and the work is not very hot! The The cost is very low. If not 50Hz into high-frequency switching power supply does not make sense

Q: In the design of switching power supply, the input power is smaller, switching transformer primary side of the inductance but the greater the? Transformer primary side of the greater the amount of inductance, the transformer is not the volume will increase?: (1) Low power is corresponding to large inductance Lp is inversely proportional to Ippk Lp = Vin (min) * Dmax / Ippk * f * k (Ippk: primary peak current K: current ripple rate) Ippk is proportional to the input power Ippk = 2Pin / (1 + k) Vin (min) * Dmax ∴Lp is inversely proportional to Pin (2) inductance volume and energy, and the relationship between the inductance is not absolute, large power is to correspond to the large volume of the inductor. In the case of a selected core L = AL * N? (AL: inductance (material dependent) N: number of turns) ∴ sense and the core material and the number of turns
