[introduction] to wisdom drive component EMC issue, I ponder over a long time, also participated in a part to check the work. Among them, crucial conclusion is: Its are probable it is prospective intelligence drives the “ bank ” that needs a hardship that span. Because well-known, wisdom driven functional security side, the requirement is slashing certainly.   EMC index is intelligence drives the “ bank “ that the function must span   Above all, cannot be equal to test…

[introduction] in use MOS the canal designs switch power source when circuit of motor perhaps drive, most person meets those who consider MOS to guide electrify block, the biggest voltage, the biggest electric current, also a few people consider these factors only. Such circuit perhaps can work, but not be outstanding, serving as formal products plan also is unallowed. One, overview of circuit of MOS canal drive   In use MOS the canal designs switch power source when circuit of…

[introduction] when we watch TV, if on the side the electric home appliances<gj of somebody use hair dryer or electric razor and so on, the snowflake streak that makes a person irritated feel can appear on screen. Electric rice cooker cooks not ripe rice, the air conditioning that shut obviously implement, pass a little while however oneself start …… these are the electromagnetism interference phenomena that often see. More serious is, if electromagnetism disturbed signal to hamper,be when the equipment…

[introduction] when with its when power source load disconnects suddenly, the big electric current on component of circuit parasitism inductance swings the aiguille voltage with meeting huge generation, the electronic component that goes up to circuit causes very adverse effect. As similar as batteries protection application, here MOSFET can keep apart input power source and other circuit come. But right now, the action of FET is not to disconnect instantly the join between input and output, reduce those having to…

[introduction] the biggest distinguish even if: The distinction of working principle and application (specific concept sees below 100 families) , former it is to use acceleration, latter is to use inertial; Former it is to be used in measure slop regulation to make the same score, latter is to know to pass know horny rate, can know the attitude of the object, so that have attitude control. Two kinds of things are to be united in wedlock to apply together…

[introduction] when put through in the high speed in high-powered applying when IGBT and disconnecting, total meeting has happened to press. For example, when shutting load current circuit, collector blasts off extremely voltage rises suddenly, reach very high peak value. By the overvoltage that switch causes can serious damage destroys switch transistor even.   How is avalanche diode helped prevent overvoltage?   Common overvoltage protection method is “ active clamp (Active Clamping)” . Below this kind of circumstance, avalanche diode…

[introduction] MEMS gyroscope also calls electronic type gyroscope, it is a chip. The gyroscope on Iphone 4 is this kind, main effect is when GPS does not have signal, the action that carries gyroscope still can continue accurate navigation.

[introduction] leakage feeling is electric machinery the first time class leaks in the process of coupling that partially magnetic flux. The lines of force that the leakage induction of transformer should be coil place generation cannot pass secondary coil, because this produces the inductance of leakage magnetism,call leakage move. Is leakage feeling in? Although printed circuit board the one part that the prints lead and transformer down-lead end that go up also is leakage feeling, but major leakage feeling is…

[introduction] capacitance (or weigh capacitance) it is the physical quantity that behaves capacitor to accommodate charge competence. Capacitance is told from physics, it is medium of memory of charge of a kind of static state, charge meets the likelihood permanent presence, this is its feature, its use is more extensive, it is the indispensable electronic component in domain of electron, electric power. Basically use at wave of coupling of wave of power source filter, signal filter wave, signal, syntonic, filter,…
