Active control based on an estimator for the bus-pumping cancellation in the half-bridge class-d audio power amplifiers

In this paper is presented a new technique to avoid the distortion generated due to mid point voltage variations on DC-Bus of Class-D Half Bridge audio amplifiers. An usual distortion source on Class-D amplifier is the Bus-Pumping effect. Bus-Pumping causes characteristic distortion and introduces a...
