Q: Do you need to consider the power to choose a regulated power supply?: Power output power can be roughly estimated, the estimated method: the maximum output power of the power supply = output voltage x maximum output current Rated output power of the power supply = output voltage x rated output current

Q: What are the main types of power supply?: Category: divided into the following four categories: AC power supply DC power supply Inverter power supply Switching power supply AC power supply Also known as AC voltage regulator. With the development of electronic technology, especially the application of electronic computer technology to various industrial and scientific fields, all kinds of electronic equipment require stable AC power supply, power supply directly can not meet the needs of the exchange of power supply to solve this A question.

Q: When the power supply is used, pay attention to what: 5. The output voltage step selector should be placed in the proper position as required before starting. 6. In the loading process does not allow the conversion step selector switch gear, if you want to change the gear to be removed after the load to convert. Like Shanghai Zhengxi regulator of the security is better. "

Q: From the old computer to remove a switch power supply can do what, can be used when the power? how to use?: can! As long as the power is enough!

Q: Input 12V, need to regulator to 5V, the supply of single-chip current sampling system, experts recommend some power module circuit or chip, requiring voltage smooth, high precision, low noise, drive capability, while the chip peripheral circuit as simple as possible: You can use high-precision three-terminal regulator IC3333 to solve. LM338-circuit parameters 1, adjustable voltage range: 1.25V-25V 2, the output current: rated 5A, instantaneous maximum current 8A 3, the voltage regulation: 0.003%

Q: The circuit teacher said the capacitor can not be 10uf, should not the same! Specifically did not say, ask the big god say, the specific capacitor should be how much ah! Check a lot, not found! Thank you!: This is nothing to calculate, are experience only. In addition the other two capacitors on the right is generally a electrolytic capacitor (large capacity) +1 non-polar capacitor (small capacity), to improve the high-frequency power output characteristics

Q: Is there a difference between a regulated power supply and a power adapter?: The first is the role of voltage regulator voltage is the second transformer power supply equipment

Q: Switching power supply and DC power supply difference: Just say it! 1 switching power supply regulator in the open and closed state of the linear power supply work in the amplification zone (specific cut-off, saturation, amplification, non-saturation in the transistor and MOSFET in the name difference) 2 switching power supply is to change the duty cycle to adjust the output According to the specific topology design can achieve step-up and step-down and linear power supply through the output sampling and reference voltage to compare the amplification to adjust the regulator tube can only step down 3 switching power supply efficiency is generally 80% of some can reach 95% linear power work to enlarge The device voltage drop is very large loss and therefore the efficiency of the lower volume of large 4 linear power supply input voltage adjustable range is relatively low The advantages of linear power can be seen from these points: Wen Bo, noise low cost of low technology mature! Hope it helps you!

Q: Why Capacitor Filtering in DC Regulated Power Supply: Rectified DC is pulsating! The high charge and low charge characteristics of the capacitor can make the pulsating current become smooth DC!

Q: Electrical Engineering! Why can not directly use a multimeter to measure the power supply of the exchange of ripple?: In general, multimeter AC can only measure the pure AC voltage. The output voltage of the regulated power supply is equivalent to the DC voltage + ripple voltage, and the multimeter exchange file can not be measured normally In addition, the ripple voltage is not necessarily a sine wave voltage, the regulated power supply itself or by external interference will produce complex ripple voltage, and the general multimeter AC voltage file is measured the average AC voltage. The ripple voltage is not a pure sine wave when the multimeter can not be accurately measured From the other side, the general linear power supply can only guarantee the output voltage in the lower frequency range of stability, and for more than tens of kHz ripple rejection is very limited. That is ripple voltage frequency is generally high, may have exceeded the multimeter AC file frequency response range, this time the multimeter is still unable to correctly measure
