[introduction] a lot of challenges that bring for the engineer in the design of the inductance in the design of switch power source. The engineer should choose inductance value not only, consider inductance even but susceptive electric current, circle line resistor, mechanical dimension is waited a moment. The article is dedicated at the explanation: The effect of DC electric current on inductance. This also can provide necessary information to choose appropriate inductance.   Understand the function of inductance   Inductance…

[introduction] we are general according to in lowest input voltage falls, below the circumstance of the biggest output, the requirement electroanalysises the ripple voltage on capacitance is calculated under how many percent. Of course, if have the demand that holds time, need to ask according to what hold time so recount, in both, take big cost.   If be below lowermost input voltage, the power input of power source is Pin, lowest inputs alternating voltage virtual value to be Vinacmin,…
