[introduction] the output voltage of rectification circuit is not dinkum dc, observe the output of rectification circuit from oscillograph, differ with dc very big, larger pulsatile part is contained in weaveform, call ripple. To obtain idealer volts d.c. , need benefit appliance has store can the reactance sex component of action (like capacitance, inductance) filter wave circuit of composition comes filter exports the pulsatile part in voltage except rectification circuit in order to obtain volts d.c. .   Circuit of…

[introduction] because Sin[ωt] is in,beg guide or can appear after integral Sin[ωt±90°] , went up to receiving so the inductance of sine wave, capacitance, when the abscissa is ωt, can observe the phenomenon of undee lead lag, see not quite easy understanding from function graph of the static state directly, still be make it animation has been compared.    Because Sin[ωt] is in,beg guide or Sin[ωt±90°] can appear after integral, went up to receiving so the inductance of sine wave,…

[introduction] diode basically can be used in all electronic circuit, its character also is special, basically be only way conductivity most, (sheet brings the resistor cent between the foot to be to two of conductivity mixing to resistor retrorse resistor two kinds) . People uses these different character to make all sorts of specific application circuit, when the diode job principle in analysing different circuit, want to use the different character of diode, choosing the what character of diode to…

[introduction] electrostatic grow results from natively attrition, the working nature of large wiring cannot avoid to chafe. Want wiring to avoid the harm that receives electrostatic discharge, the circuit that has design of FAE electron engineer with respect to consequent need is electrostatic defend the ESD protector form a complete set with plan and right choice defends the type selecting of the electrostatic protection element of plan.     Electrostatic grow results from natively attrition, the working nature of large…

[introduction] on April 9, exposition of information of electron of the 7th China (CITE2019) central grand opening can be exhibited in Shenzhen, I love program network to exhibit Ou Jingyan to appear on 6 houses A027A030 is exhibited on, development demand brings plan of network of the couplet that it is content to be propped up formidably. Spot person gas is hot, the person that attracted a lot of person of the same trades to look around stops seek advice….

[introduction] batteries is used mediumly in daily equipment more and more general. In a lot of daily products, very difficult or cannot use fill electric coupler. For example, some products need sealed crust, avoid the effect that suffers harsh environment in order to protect sensitive electron product, convenient cleanness or disinfection. Other product may be too small, cannot offer connector, and apply in batteries power supply (include shift or rotate component) in the product, cannot charge through jumper. In these…

[introduction] accuse to photograph of digital beam figuration blast, want to generate this locality oscillator (LO) , normally the implementation method of unified exam Lv is a series of Suo Xianghuan allocation to the middle of array of line of distributinging Yu Tian commonly used and fiducial frequency. To annulus of these distributed lock photograph, in looking preamble is displayed, still use at evaluating the method that combines phasic noise function without sufficient record.   In distributed system, collective noise…

[introduction] power factor (Power Factor) it is a coefficient that measures discretion of electric equipment efficiency. The bear property of its size and circuit is concerned, the power factor that waits for resistor bear like furnace of incandescent lamp, resistor is 1, the circuit power factor that has inductance sex load commonly is less than 1. Power factor is low, the specification does not have result power big, lowered the utilization rate of equipment thereby, increased loss of circuit power…

[introduction] in often be being operated actually, the biggest to systematic loss is low frequency in all modular interference, electric machinery of for example high-power, breaker or switch, short circuit, induction of be struck by lightning, these types are ab extra mostly in all modular signal, its arteries and veins is wide arrive in hundreds Us between S, cycle is the longest also be several seconds, such pulse causes the tall voltage wave motion to the ground continuously, injure a…
