mosfet irfp260

This Hi-Fi amplifier circuit is suitable for a lot applications like general purpose amplifier, guitar amplifier, keyboard amplifier. The amplifier can be also used as a sub woofer amplifier but a subwoofer filter stage has to be added before the input stage. The amplifier has a low distortion of 0. Capacitor C8 is the input DC decoupling capacitor which blocks DC voltage if any from the input source.

IF unblocked, this DC voltage will alter the bias setting s of the succeeding stages. Resistor R20 limits the input current to Q1 C7 bypasses any high frequency noise from the input. Transistor Q1 and Q2 forms the input differential pair and the constant current source circuit built around Q9 and Q10 sources 1mA.

Preset R1 is used for adjusting the voltage at the output of the amplifier. Resistors R3 and R2 sets the gain of the amplifier. The second differential stage is formed by transistors Q3 and Q6 while transistors Q4 and Q5 forms a current mirror which makes the second differential pair to drain an identical current.

This is done in order to improve linearity and gain. Power amplification stage based on Q7 and Q8 which operates in the class AB mode. Preset R8 can be used for adjusting the quiescent current of the amplifier. The network comprising of capacitor C3 and resistor R19 improves high frequency stability and prevents the chance of oscillation.

F1 and F2 are safety fuses. Set R1 at midpoint before powering up and then adjust it slowly in order to get a minimum voltage less than 50mV0 at the output. Now adjust R8 so that the multimeter reads A basic dual power supply is used for the amplifier circuit.

If 6A ampere bridge is not available, then make one using four 6A6 diodes. C10 and C11 are high frequency bypass capacitors. Filter capacitors C8 and C9 must be at least uF, higher the value lesser the ripple. I have transformer of 3 amp.

The sound is superb. Thank you sir for the PCB layout. If no, then what should I change in power supply??? What is the purpose of the resistors R1 and R8 being variable?

Also what use capacitors C1 and C2 in parallel? Why not use a single capacitor? R1 to make zero current flow thrbough speaker. R8 to adjust no signal current adjustment of 50mA. C1 is used to take care of HF decoupling, as C2 is wound capacitor with inductive componunt and for LF decoupling.

Pretty useless. If you try to build, it will not work, as they have not included a lot, what you see is only the tip of the ice-burg. Hi sir, I am planning to make a 2. The spec is given below, also I have some doubts regarding the project. It will be great if I get your valuable suggetions. I think preamp will just only increase the voltage level of the input signal, but when we split a signal into two actually the current is divided into two.

Will the preamp be helpful in current gain? I will use hz lowpass filter before the subwoofer amplifier, do it act as a preamp? In common I have seen bass and treable control knobs in amplifiers but I want to use low, mid and high controls, is it okay?

I am planning to fix all these circuits in a single casing so can i use a single transformer to the entire system, if yes please specify the voltage and amps. I want to add a short circuit or overload protection fuse in this system, suggest some links to get some idea about this. One woofer, midrange and tweeter will be connected parallely to the one channel of stero amplifier, so I think two 8 ohms drivers can make 4 ohms load.

Do the tweeter have impedence? Im also planing to do a LED spectrum analyser and digital volume controls with remote. These features will be added later. If u have ideas about these please share.

I have check voltage across drain to source of Q8 n Q7 Q7 drain to source and drain to gate is 37 volts Q8 drain to source and drain to gate is 71 volts. The amp works fine.

Of course R17 must be ohm. With 47 Kohm you get no sound, Q1 and Q2 remains closed. Which are the resistances burnt. This give a clue about your problem. Hope you have kept R1 at center and R8 at minimum value before switching on your amplifier. The resistors seems to be fine.

I disconnected the circuit from mains quicker than the fuses. Could the root of this problem be an overheated transistor when soldering? Once things are fine set current adjusting pot to minimum value switch on with new MOSFETS and with a dummy load of 25 ohms without speaker.

If things are ok set the current as recommended, and connect 8 ohms speaker and try. As I powered up, Q5, Q6, and Q7 blew up. Something must be terribly wrong with my circuit. Any suggestions on where the error could be located? It is a temperature compensated constant current mirror. The current through Q5 and Q6 will be identical. If i connect 25v 5amp ac and 10inch 4ohm subwoofer, what power will actually get when it use as a subwoofr amp?

Please help me sir. You cannot use 25 volt transformer. With this power supply and 4 ohms load speaker you will get watts RMS output power. Can i use it as a subwoofr amp? What power will get when i connect 10inch 4ohm subwoofr? Hi BC VCeo is 80 volt but is only 50volts, hence it will be oprating at the brim and may get damaged, hence it is preferable to use BC only. If you are using 2 similar amplifiers yes with proper insulating kits you can use provided the sink is sufficiently big to take care of the generated heat.

If heat sink temperature is used for thermal compensation it cannot be used. It is a better practice to use separate heat sink for each different application. Is this corect? Pls seed! Hi you are correct it should be 33mV.

If I power up six of these with the same power supply, what value should each rectifier diode have? Hi Chiliman the bridge rectifier should be capable 25amps. Instead I would like you to use separate filters and rectifier for each amplifier, you mount bridge rectifier and filter capacitors of the value shown in each circuit board.

Use a single transformer may be torroid one capable of 20amps capacity. First of all i want to tell you that its a VERY LOUD amplifier even with dual 27V transformer,i will try it with 40v when i buy the new transformers, i have only one question, what kind of pot is the ideal to adjust the volume?

I use a k pot but when i turn it off i stil have sound in my speakers, a 1M ohm pot would be good or even it will be small? Thank you very much!

Hi Theofrastos K logarithmic control that should take care for volume problem at lower settings, do not use Lin controls. Hello, both my transistor burned out in 2 secounds Q8 and Q7 , what can cause this problem? Thanks for the help. Hi Niklas in the place of R8 put a link. Reduce the fuse rating to mA. If every thing is oK it should stay alright if the fuse blows indicates something wrong in the wiring.

Please check and correct and proceed as above. If it is ok replace link with say 2k2 pot and set the current through the fuse for 50 to 60 mA. Hi… plz, provide me the pcb layout. Am I missing something or should the measurement be across just 1 x 0. Thanks, Baz.

Hi Harry as per following link it is a good performer. Hi Harry can be used. This escheme was not designed for this author. This amplifier work fine, but in the scheme displayed here, have some issues.

In this lengthy blog, I go over detailed instructions on how to make a small, simple, tuneable induction heater that can easily melt steel and other metals and uses a half bridge of IRFPN mosfet transistors. The tank circuit is driven to resonance by a timer resonator. Induction heating is the fascinating ability to wirelessly heat metal or graphite objects without the use of an open flame and with minimal wastage of heat to the surroundings. It is not a new phenoma and has been around for more then years. It is widely used in the smelting and automobile industry because it can easily be controlled, and scaled.
