Ciri ciri rippe tinggi, atau osilasi pada power class d

In a Class D amplifier system, the audio signal is converted into a high-frequency pulse waveform (PWM) before being amplified. However, if this process is not properly controlled, frequency oscillations and high voltage ripple can occur at the output. High-frequency oscillations occur due to imbalances in the feedback circuit, suboptimal PCB layout, or the presence of parasitic inductance and capacitance. This condition causes the signal to oscillate wildly outside the amplifier's ideal operating frequency. Meanwhile, high ripple occurs due to an inappropriate output LC filter or poor power supply quality. This ripple can produce noise, overheating of the MOSFET transistor, and audio distortion that can sound harsh or unclear. To overcome this, precise circuit design, the use of high-quality components, good grounding and filtering, and proper feedback compensation are required to maintain the amplifier's stability and efficiency. #poweramplifier #audiodiy #bluetoothamplifier #classd #classdamplifier #diymobil #diyspeaker #electronics
