Kurzfassung englisch:
In this paper a promising novel output voltage filtering concept for multi-cell switch-mode power
amplifiers is analyzed. The proposed hybrid filtering concept is based on a passive LC filter
enhanced by a linear-mode correction stage of small rated power. Using this principle, also
"sub-harmonic" (i.e. low-frequency) switching noise distortions (typically appearing in real interleaved
multi-cell switching amplifiers) can be effectively suppressed which is not possible using conventional
LC filters. Combining the new hybrid filtering approach with a switch-mode power amplifier formed by
an arrangement of low-voltage MOSFET switching cells finally results in a power source of high
output voltage precision at high efficiency rates.
