Q: Half-bridge switching power supply and the commonly used by the three-terminal regulator block compared to the power supply, what are the characteristics: Switching power supply work in the conduction and cut off the two areas, the work of low heat, low power consumption

Q: From the old computer to remove a switch power supply can do what, can be used when the power? how to use?: Yes, the main power is enough power. Voltage and current are appropriate.

Q: DC power supply CH1.CH2 two channels with wire connection and not connected What is the difference: This type of CH1 CH2 is output independently. Two channels do not need to be connected. If you want the two channels to be output in parallel or in series, you only need to press the front panel of the parallel button or series button.

Q: What are the differences between linear regulated power supplies and switching power supplies?: Switching power supply is through the DC into a high-frequency pulse, and then the electromagnetic conversion to achieve voltage conversion and regulation.

Q: What is the switching power supply?: A new type of power supply designed by the semiconductor device to turn on and off two extreme states corresponds to a linear power supply. Such as mobile phone charger, its efficiency is generally more than twice the linear power supply. Distinguish between two kinds of power: switching power supply is very small and very light, there is a very small transformer, and linear power is relatively heavy, the transformer is a major part of the power supply. Is a very complicated technology, very promising.

Q: Switching power supply and DC power supply difference: I think you should ask is the difference between switching power supply and linear DC power supply right? Switching power supply is the unstable DC power through PWM or other means into a series of pulses, and then these pulses to rectify and filter to get a stable DC power supply, this approach is relatively efficient. Linear power supply is through the way to get a stable power supply, low efficiency.

Q: Use 7812 to make a positive 12V DC power supply Is 220V AC voltage correction 12V: The secondary voltage of the transformer is preferably set to about 12.5V. Because 12.5V sine wave AC voltage peak is 17.6V, after the bridge rectification after 15.2V ~ 15.4V, and 7812 instability voltage is 2V, generally leave about 1V margin is about 3V more appropriate. If the transformer secondary voltage is set to 16V, the peak is 22.6V, after the bridge rectifier over 20V, 7812 to dissipate the power of 8V × output current, when the current reaches the rated 1A, 7812 own power consumption More than 8W, will be very hot, and may even be damaged due to overheating.

Q: Power supply 4.5v can drive 3.6v lithium battery: Can charge. But to the late to be careful, do not overcharge.

Q: Switch DC power supply is what it means: Commonly speaking, switching power supply is AC rectifier filter, and then through the crystal switch and a certain voltage regulator circuit, the switching transformer output high frequency voltage and current, rectified filter output stable DC power supply. "Best answer"

Q: It is required to output 0-250V continuously adjustable AC voltage in the case of mains input fluctuation. The load is only one coil of 800 ohms, so the power consumption is very small. What are the recommended models? how's the price?: Then you do not use the regulator directly on the OK? I give you a regulator of the power to see how much power you need, the price is not expensive.
