| Popis: | A voltage-mode boost converter is analyzed. Due to changes of the input voltage converter exhibits different steady-states. The change of steady-state from period-one to quasiperiodic steady-state is observed. The increase of inductor current due to that change is much larger than due to any other change of steady- state. The increase of inductor effective current increases inductor copper losses while the increase of inductor peak current increases switches current stress. The significant increase of effective value and peak value in quasiperiodic steady-state is not well known to the switching power converter community, so it is important fact that must be taken into account when designing the boost converter. |
