A Class D power amplifier is a type of amplifier that uses pulse-width modulation (PWM) or similar techniques to convert the input signal into a series of high-frequency switching signals. These amplifiers are highly efficient, often exceeding 90%, because they minimize the time transistors spend in the high-power dissipation states. As a result, Class D amplifiers are commonly used in applications where power efficiency is crucial, such as in portable audio devices and high-power sound systems.
