In charging process, switch closes (triode ON), and switch (triode) place wire replaces.At this moment, input voltage flows through inductance.Diode prevents electric capacity from discharging over the ground.Because input is direct current, so the electric current on inductance linearly increases with certain ratio, this ratio is relevant with inductance size.Along with inductive current increases, in inductance, store some energy.
Equivalent electrical circuit when switch disconnects (triode cut-off).When switch disconnects (triode cut-off), due to the electric current retention performance of inductance, the electric current flowing through inductance can not become 0 at once, but becomes 0 from value when charging complete slowly.And original circuit has disconnected, so inductance can only be discharged by novel circuit, namely inductance has started to capacitor charging, and electric capacity both end voltage raises, and now voltage is higher than input voltage.Boost process is exactly the energy transfer process of an inductance.During charging, inductance absorbs energy, and during electric discharge, inductance releases energy.If electric capacity is enough large, so a lasting electric current just can be kept at output terminal in discharge process.If the process of this break-make constantly repeats, the voltage higher than input voltage just can be obtained at electric capacity two ends.
