Q: What is the difference between a frequency conversion power supply and a frequency converter? I believe everyone has many questions. I only know that the frequency conversion power supply is not the same product as the frequency converter, but I don't know much about it, some friends may know that the inverter is used for speed control, while the inverter is used to simulate power usage in factories. This explanation is correct, but you know the internal reason why it cannot be used in the sa

the ends of the antenna. Several different variations of the dipole is also used, such as thefolded dipole, short dipole, cage dipole, Bow-tie, an D batwing antenna. Dipoles May is used as standalone antennas themselves, but they is also employed as feed antennas (driven elements) in MA NY more complex antenna types, such as the Yagi antenna, parabolic antenna, reflective array, turnstile antenna, log perio DIC antenna, and phased array.Dipole characteristics 1.

It is the front of many inverter circuits, which can carry out the pressure, then what is his concrete realization idea? What are the impact variables? What are the characteristics? What is the essence? These should be questions that are of interest to beginners, including me. According to some of our previous impressions, Buck can be distributed by resistive load, while a transformer can achieve a lifting pressure. The transformer utilizes the induct

transient pulse damage is to bring the instantaneous current from the sensing element.The TVs two pole is on the circuit board with the protected line, and when the transient voltage is over the circuit, the voltageThe TVs two pole produces an avalanche that provides an ultra-low resistive path to the instantaneous current, which results in instantaneous currents being induced through the two-polar tubes,Avoid the protected element and keep the prote

Another is the resistor, in the device library, it is also simply referred to as RES1 and RES2, whether it is 100ω or 470kω are the same, for the board, it is not related to the Ohm number, completely according to the resistance of the power of the choice of the 1/4w and even 1/ 2W resistor, can be encapsulated with AXIAL0.3 components, and a large number of power, the use of axial0.4,axial0.5 and so on.

. Characters printed from the hard drive label can give us some useful information, such as "Barracuda" on behalf of the Cool Fish series, "7200.10" refers to Seagate 7200 turn tenth generation products, a single disc capacity of 250GB, If you change to 7200.9 or 7200.11, it means the Nineth and 11th generation products of the Seagate Cool Fish, with a capacity of 250GB.

calls for IO multiplexing. When any data arrives in the IO multiplexing queue socket , or the write buffer is idle, the epoll return of the call can be triggered, otherwise the call is blocked epoll . The actual sending and receiving of the data is done in the purple thread. Therefore, in order to improve the throughput, the and all of a socket read write should use a non-blocking mode, so as to maximize the system throughput. For example, if you are blocking a socket call write , you will not

many consumer electronic display products, touch technology has also completed the transition from resistive touch to capacitive touch control. As one of the key materials of capacitive touch screen, the cover glass has irreplaceable status, especially high aluminum cover glass, high growth rate and excellent market prospect in 2016. In addition, color filter, polarizer, ITO, liquid crystal materials, such as basic material technology threshold high,

The achievable accuracy for systems and multiple ADCs depends directly on the reference voltages applied to the ADCs. Medical-ultrasound-imaging systems, for example, commonly include a large number of ADCs in the system ' s Beam-former elect Ronics, with the ADCs usually organized in groups of--- To obtain maximum beam accuracy, you must minimize errors in the ADC path. Poor accuracy of the reference voltages of the individual ADCs degrades the overall system accuracy. Another source of degrada

for maximum ripple current (b Oth in frequency and magnitude). This ripple current can cause damaging heat to being generated within the capacitor due to the current flow across resistive Imperfections in the materials used within the capacitor, more commonly referred to as equivalent series resistance (ESR). For example electrolytic Tantalum capacitors is limited by ripple current and generally has the highest ESR ratings in The capacitor family, wh
