PCB Layout Power Amplifier Class-D Behringer B215D IRS20957 pdf Class D Power Amplifier circuit is on the rise especially in recent years due to its very high efficiency and relatively cheap price and Advantages of Class D Power Amplifier Circuits The advantages of class D power amplifiers are: Efficiency on supply power requirementsSimple physical sizeCool design and very practicalThe heat produced is very minimal Class D audio amplifier is a switching amplifier or PWM as previously explained. By applying the Switching model it can reduce the power loss in the final amplifier and allow for the efficiency of 90% - 95%. The input audio signal is used to modulate the PWM carrier signal that drives the final amplifier. Before being fed to the speaker, the Low Pass Filter (LPF) is passed to eliminate the high-frequency PWM carrier. And on this occasion I will share the schematic along with the PCB layout for the D-class power amplifier, the Behringer B215D schematic power amplifier y...

Problem RGB TV Cina Yang Sering Menjebak Teknisi "> Diantara problem kerusakan TV Cina yang sering menjebak teknisi adalah bagian RGB. Ini dari hasil pengamatan Admin ketika membantu teman dalam menangani kerusakan seputar RGB TV Cina. Banyak sekali kesalahan prediksi yang berujung pada gagalnya menyelesaikan pekerjaan servis. Diantara problem RGB yang paling sering Admin temukan dan tidak semua teknisi paham dalam memperbaikinya adalah: Gambar buram kadang seperti pelangi berkabutGambar dominan di warna tertentuGambar muncul warna tertentu disertai dengan garis-garisGambar seperti kliseGambar blank putih bergarisWarna seleberanDan masih banyak lagi. Nah dari semua problem atau kerusakan seputar RGB TV cina diatas, akan saya bahas satu-persatu tentang penyebab pasti dan cara memperbaikinya. 1. Gambar buram kadang seperti pelangi berkabut Gambar buram dan terkadang seperti pelangi dipenuhi kabut sering dianggap teknisi adalah kerusakan tabung sudah lemah atau FBT rusak. T...

DIY 500W Class-D TL494 Switching Amplifier Publisher  Elcircuit LCSC Electronic Components - More Asian Brands, Lower Prices Sign up today and get $8 off on your first order In this project, I will share about class-d power amplifier using TL494 IC for PWM, and use N-Channel MOSFET transistor as the final amplifier. This circuit is not so complicated and cheap to make practice making power amplifier class-d. This power amplifier circuit can be supplied with 30V to 100V DC asymmetric power supply using 8VDC bias voltage up to 12VDC. For the output power of this amplifier can generate power up to 500Watt, pretty good is not it? to make this power amplifier please see the circuit schematic of TL494 Power Amplifier below along with PCB Layout design that you can download in the form of .PDF format. Part List: R1=1K R2,R5=47K R3=10K R4=470R R6=8K2 R7=56R R8=2R2 R9=470R R10=56R C1=1uF/16V C2, C3=1N C4, C6=10uF/50V C5=2N2 C7, C9, C10=220uF-1000uF/100V C8= 100N/400V ...
