The Class D Amplifier, or PWM Amplifier, has almost constant efficiency regardless of the output current in the practical region. However, the efficiency of the Class B Amplifier, or Analog Amplifier, is only 20% to 65% efficient. Therefore, the loss of the output stage can be greatly improved by the PWM Amplifier.
