On this occasion, I will share the power amplifier circuit, power amplifier circuit with the class-d system. The power amplifier is very good used for large power. This power amplifier can be supplied from 65V to 95V DC with a minimum current of 10A or better. And can generate power up to 1500Watt RMS, so big is not it?
The D-class amplifier is an electronic amplifier that uses transistor switching as the primary method for power, unlike class A, class B, or AB-class linear amplifier that uses the active resistance of the transistor. Therefore, this amplifier has a higher benefit, with additional results for the required heat sink. Filter the LC pass under smoothing the pulses.
The efficiency of a high D-class amplifier stems from the fact that the output stage never operates in a linear or active state. The output of the D-class amplifier consists only of ON or OFF. When the appliance is alive, the current that flows is maximum, but the voltage that runs it is ideally zero, and when the appliance dies, the voltage that stretches it is maximized, but the current that flows is zero.
