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.
Q:Switching power supply efficiency
for example, the output current is 10A / 2V, when the diode conduction voltage is 0.7v, the loss is 0.7 * 10 = 7 watts, the transformer output (2 + 0.7) * 1 = 27 watts, the available power of 20 watts, the efficiency of about 73%;
Q:Is the DC power supply a switching power supply?
DC is the direct current (Direct current), do not know if there is no misspellings Switching power supply is AC-DC, such as 220V home AC, into a charger 5V DC
Q:Switching power supply control chip selection: UC3844, VIPER series, topswitch series. What is good?
TOP and VIPER than: really TOP than VIPER price of your point, but the high frequency of 40K it, in fact, TOP223 can replace the VIPER, you do 20W output looks like TOP223 is not enough because the 223 wide range of input 85-265AC can only do 15W (P or G package), Y package 223Y can do 30W, but have to leave the margin? And 3844 compared to the first two: you can freely choose the appropriate MOS tube, higher operating frequency, a variety of forms of protection. The above is a more obvious difference, the specific or look at the cost of indicators required. You do not know how to use the multi-channel regulator with three? Cross adjustment rate has been a tune! Haha
Q:The switching power supply has no output but the low side indicator flashes
3842 6 feet is the chip output pin, if burned there, it is likely that the chip and switch are broken But the power output there is voltage, although unstable, indicating that the chip and switch is still working. You can test the chip 7 feet voltage is stable, if the stability of the power supply is likely to have problems on the low side. 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. Indicator light: There is always a light on a key switch for a home lighting. This indicator light is extremely large, so that the circuit current is minimal, so that the voltage in the night with the electrical voltage can not reach the rated voltage can not be bright, under normal circumstances this indicator has a capacitor, because a small The indicator light can not accommodate the voltage of 220v.
Q:Computer switching power supply voltage value
Power supply test As a source of personal computer power, but also with the progress of personal computers and change. From the previous 100W AT power supply to today's 450W or even higher ATX power supply, not only the power in continuous climb, the output current is also increasing, +5 V output current has more than 30 amps. Since the announcement of the ATX2.01 power supply standard in January 1998, after the production of power are compatible with this standard, but the output voltage of each voltage is increasing. We use the ATX switching power supply, the output voltage of + 12V, -12V, +5 V, -5V, +3.3 V and several different voltage. Under normal circumstances, the above-mentioned several kinds of voltage output range allows the error is generally within 5%, as shown in the table below, can not have too much range of fluctuations, or prone to crash data loss situation.

Q:Switching power supply inside, after the transformer after the current is alternating current or DC ah
Alternating current. AC power through the transformer or AC, transformers and generators, like the use of the principle of electromagnetic induction to achieve the purpose of voltage conversion. But in life, the radio power output is DC, which is because after the transformer buck after the alternating current from the power supply in the rectifier circuit and filter circuit into DC. Generally between 3-9V. Alternating current (alternating ≈ltərˌneɪt) current [kɚrənt, kʌr-]), referred to as AC. AC also known as "alternating current", referred to as "exchange". Generally refers to the size and direction of time with the periodic changes in the voltage or current. Its most basic form is sinusoidal current.
Q:Switching power supply and communication power difference
Communication power is the power of the communication equipment. Can be a battery, 220V AC, generators, dry batteries, cell phone batteries, etc., because it is used for communications equipment, it is generally through the high-frequency oscillation of electronic circuits (switching power supply)
Q:Switching power supply output 12V 10A how to use the transformer how much ah
Switching power supply does not need the front side of the transformer ah, in our country, 100V - 260V, 50 / 60HZ under normal use. Do not repeat the mistake again. {Single-phase electric power = voltage × current × power factor that is P = U × I × cos ¢}, and the voltage multiplied by the current that is the power factor cos ¢ = .1 case, only for pure resistance circuit. The switching power supply circuit is an inductive load, and the inductive and capacitive loads have a power factor
