WebClass G and Class H are quests for improved efficiency over the classic Class-AB amplifier. Both work on the power supply section. The idea is simple. For high-output power, a high-voltage power supply is needed. For low-power, this high voltage implies higher losses in the output stage. WebClass D amplifiers have the following features: 1. Output power Class-D amplifiers can produce high levels of output power, which is why they are used in applications where high efficiency is needed. Class D amplifiers can power speakers, subwoofers, and other devices with an output of up to 200 watts per channel.

WebIntroduction. Class A amplifiers offer a very good linearity of the output, meaning that the signal is faithfully reproduced, however their efficiency is very low, around 20-30 % in most of the cases. On the other hand, class B amplifiers present a very high efficiency up to 78.5 % but cannot reproduce the output faithfully. Indeed, a crossover distortion appears … WebThe class A, B and AB amplifiers are called as linear amplifiers because the output signal amplitude and phase are linearly related to the input signal amplitude and phase. Class C Power Amplifier. When the collector current flows for less than half cycle of the input signal, the power amplifier is known as class C power amplifier.
