[introduction] the relevant knowledge that the article basically introduced to be classified about disturbing power source filter, emphasized series of pair of filter of interference power source to have a description. Filter wave is one of signal processing main idea, the action of filter wave circuit is the communication composition in reducing pulsatile volts d.c. as far as possible, withhold its to shed part continuously, make coefficient of output voltage ripple is reduced, weaveform becomes more flowing. Generally speaking, filter…

[introduction] batteries group is by many batteries (it is the lithium ion batteries in pure electric car normally) compositive array, can produce the tension that is as high as hundreds bend over. The voltage of batteries group depends on the systematic demand of electric car. If plan institute is shown, electric car (EV) main transmission system is comprised by 3 systems module.   The 2nd component of the system is inverter. The AC traction electric machinery that electric car uses…

[introduction] the working principle of capacitance step-down is not complex. His working principle is to use capacitance to issue the capacitive reactance of generation to restrict electric current of the biggest job in certain communication signal frequency. The working principle of capacitance step-down is not complex. His working principle is to use capacitance to issue the capacitive reactance of generation to restrict electric current of the biggest job in certain communication signal frequency.   For example, below the labour frequency…

[introduction] recommend touch when accusing MCU to give a client, classics regular meeting has such feedback: We ever were used touch accuse IC, use easily simply. So, touch accuse MCU and touch accuse IC after all which be right choice? Pure the oneself function characteristic from them, cannot say or state with certainty bad of what actor what. Can say only, certain application suits to use more touch accuse IC, and some application suit to use more touch accuse MCU….

[introduction] the series that capacitance discussed on reference book and paralell connection, but should notice that is to be aimed at without polarity capacitance character. This example comes from a good still text book below. The answer is to calculate was opposite, but, do not accord with the train of thought that solves project problem and causal. Because, cannot treat the title as problem of a maths, make mathematical calculation only, and oversight the meaning of physics and project.  …
