The function can be converted into algorithm computable for microprocessor by z-transform.It obtains：
U[n]=A1U[n-1]+A2U[n-2]+B0E[n]+B1E[n-1]+B2E[n-2]。

Sense.Therefore, in order to realize the present invention described here, the match parameter B0 to B2 during the runing time of adjuster, wherein
Especially it is noted that：Only change parameter before or after adjusting the calculating of algorithm.If changed in the adjuster computing interval
It carries out, then this may cause uncertain adjuster reaction or even results in the oscillation of adjuster.
According to the present invention it is possible to which parameter is made to also depend on other parameters (input voltage, output voltage, temperature).Parameter group
Number it is unrestricted, such as it is contemplated that look-up table, the look-up table distributes a parameter group to each current value.The present invention is not
It is constrained by booster converter.It can adapt the invention to any other converter, that is to say, that be suitable for all with electricity
The DC-DC converter of sense and capacitor.The present invention is not limited to CCM converter and can also be suitable at running turn of DCM

If in voltage lifting PFC (Power-Factor-Correction：Power factor correcting) in audio-frequency amplifier electricity
Make in the part of source in this way adjust come corrector choke inductance decline, then can be realized by this method：Entirely working
Choke currents are optimally adjusted in range and therefore adjust power network current and at the same time realizing as far as possible in each operating point
Good power factor.
It can be prevented simultaneously using biggish choke coil that may result in higher manufacturing cost, new.
Therefore, according to the present invention, depending on for the winding material in switch application is obtained by dynamically adjusting to match
The compensation of the inductance decline of electric current.
