Many suppliers offer peak limiter modules for high voltage audio amplifiers. Figure 11 - Diode Clipper And Filter Circuit. The drawing above shows a suitable diode clipping network, along with the high and low pass filters. The maximum signal level is limited to about 1.3V RMS before the clipper starts to limit the peak amplitude.

Hello folks, I want to build an audio power amplifier, but not for music use. The objective is to build an AC power supply. A signal generator that can output between 40 Hz and 400 Hz will drive this amplifier, which will output up to 250 Vrms. The output will be feedback controlled to the adjusted voltage level.

This high power audio amplifier circuit consists of a differential amplifier as first stage amplifier. Potentiometer VR1 is used to adjust the offset voltage of the amplifier before entering the next level. Transistors Q7 and Q8 on this amplifier circuit serves as protection against short circuit, which flows out through the final stage transistor will be limited to about …

The purpose of the supply is to convert the auto's battery voltage to a higher voltage. For example, if an amplifier is to produce 100 watts into a 4 ohm speaker, we need 20 volts RMS. This implies that we need about +/-28 volts. (20 volts R.M.S. = 28.28 volts peak). We call that the "rail" voltage.

A straightforward analog implementation of an audio amplifier uses transistors in linear mode to create an output voltage that is a scaled copy of the input voltage. The forward voltage gain is usually high (at least 40 dB). If the forward gain is part of a feedback loop, the overall loop gain will also be high. Feedback is often used because ...
