3000 Watts Power Amplifier Class D Mosfet IRFP260 / IRFP4227

3000 Watts Power Amplifier Class D Mosfet IRFP260 / IRFP4227


3000W (3kW) Class D Power Amplifier Project using IC IR2110, CD4049 (HEF4049/HCF4049), NE555, LM311, and Op-Amp Comparator TL071 as the main stage amplifier, the driver stage using BD140/BD139 or you can use any driver stage power amplifier transistors. The Final Stage Amplifier using 4 x Mosfet Transistor IRFP260 or you can use IRFP250 / IRFP460 / IRFP4227. And do not forget to lose the importance of the LPF Filter.

The advantages of this high power amplifier are:

Strong Bass Boost, not SaggySecondary comfortable bias voltage (can be AC (transformer) / DC (adapter))Highly Efficient Rail - Stack LayoutOversized Heatsink & Output Coil (not easy saturation)Pulse Resolution Adjust Enable

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

Power Class-D D2K Full-bridge Amplifier

Power Class-D Full-bridge Amplifier - D2K PCB Gerber File Before I share PCB Layout about full-bridge class-d power amplifiers with 2000W power I will tell you a little more about class-d power amplifiers. Class D amplifiers are known as PWM (Pulse Width Modulation) amplifiers or Switching amplifiers which are now increasingly popular in use. Replaces the class AB amplifier that has been used a lot before Then what is the D class amplifier like? And what are the advantages? Class AB amplifiers have a relatively large "power dissipation" (loss of power) that requires a large amount of heat sink. The greater the power (Watt) of class AB amplifiers, the greater the cooling needed. Here there is more or less a power loss of about 25 ~ 40% which turns into heat, which must be removed through the cooler. Class D amplifiers produce almost no heat so they don't need a cooler. The efficiency achieved is close to almost 100%, only requires a little space and a few supporting

High Power Class-D Amplifier D4K5 This High Power Amplifier circuit is a class D power amplifier, which has a high enough power to generate 1000W of power at 8 Ohm impedance - and also more power up to 2000W at 4 Ohm impedance. This Power Amplifier can generate great power if given enough power supply. For example, you can use 30A transformer with 100V symmetric voltage.  Here is the circuit scheme of High Power Class-D Amplifier D4K5: View larger schematic image here:  Power Amplifier Class-D D4K5 Component List Resistor R1, R3, R4, R9, R13, R18, R19, R20= 1K R2, R16, R39= 100K R5, R6= 10R R7, R8=6K8/2W R10, R21, R26, R27=4K7 R11, R17=6K8 R12=100R R14, R15=4R7 R22, R23, R24, R25, R31, R33=47R R28, R29, R30=0,1R/2W R36, R38=22R/2W R40=1K5/5W R41=10R/2W RV1=10K Trimpot Capacitor C1=10uF/16V C2=10N C3, C4=1N C5=470uF/16V C6=220uF/16V C7, C9, C11, C12, C13, C15, C16, C18, C19=100N MKP C8=470uF/16V C10, C14, C17=100uF/16V C20=10uF/50V C21, C22, C23=220N/475V
