| Abstract |
The reduced semiconductor voltage stress makes the multilevel inverters especially interesting, whendriving capacitive transducers for audio applications. A ± 300 V flying capacitor class D audio amplifierdriving a 100 nF load in the midrange region of 0.1-3.5 kHz with Total Harmonic Distortion plus Noise(THD+N) below 1 \% is presented. |
