摘要： Audio amplifiers are used in many known forms in music systems, for example for domestic use or for playing music in cinemas, discos etc., but also in public address systems, as are known, for example, in public buildings, schools, universities etc. for making announcements. The invention proposes an audio amplifier (1) for amplifying an input signal into an output signal using an output amplifier stage (6), wherein the output amplifier stage (6) is designed to amplify an intermediate signal into the output signal, and wherein the output amplifier stage (6) is in the form of an amplifier which operates in switching mode, and having a limiter device (4) which is designed, from a program and/or circuit point of view, to generate the intermediate signal on the basis of the input signal, wherein the level of the intermediate signal is always limited as a function of an adjustable maximum level in such a way that the output signal does not exceed the maximum level independently of the input signal.

摘要： An amplification device, comprising a device input receiving a device input signal, an amplifier unit comprising a zero crossing detector unit, an output filter and a lead-lag compensation network. The zero crossing detector unit compares the device input signal with a reference potential and switches a pulse width modulated detector output signal between first and second voltage levels dependent on the comparison. The amplifier unit provides an actual device output signal, e.g., an amplified representation of the device input signal. The amplification device further comprises a device output providing the actual device output signal, a control loop bridging the amplifier unit and comprising a forward filter, e.g., an integrating filter, for increasing loop gain improving the signal-to-noise ratio of the actual device output signal, and a deviation detection unit detecting over modulation of the amplifier unit, so that the amplification device disables forward filter functioning upon over modulation.

摘要： A half-bridge three-level pulse width modulation (PWM) amplifier includes a prescaling unit, a PWM generator configured to convert the input signal to a three-level PWM signal having a first level, a second level and a reference level and an output stage. The prescaling unit scales an input signal according to at least one gain value to provide a scaled signal. The PWM generator varies the width of pulses having the first level and varies the width of pulses having a second level based on the scaled signal. The output stage drives an output node to a level of a first power supply voltage, a second power supply voltage or a third power supply voltage based on the three-level PWM signal. The output node is connected to a load. The magnitude of the at least one gain value compensates for variations of power supply voltages.
