Why does my PSU make a ringing noise?Whenever I play certain games my power supply seems to make a high-pitched ringing noise. I heard somewhere that it could be that I'm overloading my PSU but I doubt that. Another thing I heard is that the USB cable could be touching the HD audio cable and it can create that noise.
Why does my power outlet make a buzzing sound?Buzzing sounds are especially common in grounded outlets, which protect the outlet and device from an electrical surge. But if you hear a louder buzzing sound right as you go to plug something in, that could be an issue. In this case, the buzzing sound is most likely a loose connection between the outlet and the plug.
What happens if you add noise to a power supply?Noise added to the power supply can cause the product to malfunction. Noise can also lead to performance problems. For example, it can affect the audio from audio equipment and the video from video equipment. There are several countermeasures against ringing.
Why does my electrical panel make a popping sound?Despite sounding a little different, a popping sound is also commonly a result of electrical arcing. This is because a brief electrical arc is almost like a miniature explosion as the electric current jumps between connections almost instantaneously. You can hear this sound both at an outlet or at your home’s main electrical panel.
What causes ringing in a receiver?As the input impedance of the receiver becomes increasingly higher than the output impedance of the driver, the amplitude and duration of ringing increases. Ringing can also be caused by parasitic components such as parasitic inductance and parasitic capacitance.
How does ringing affect a SW MOSFET?・ Rise and fall times of SW MOSFET are several ns. Ringing has various negative effects on a product. First, higher current flows through the circuit. This increases the power consumption of the product and generates heat. This may reduce the performance of the individual devices on the board and shorten their li
