Use a single transformer may be torroid one capable of 20amps capacity. At the gate-source voltages needed to obtain typical bias currents, even a small temperature increase causes a large drain-source current increase, so the use of a carefully designed bias servo Q5, R5 and R6 in the Figure 4 schematic is absolutely essential. Preset R1 is used for adjusting the voltage at the output of the amplifier.

In every practical design I have tried I had to use a class AB driver datasheet.

I disconnected the circuit from mains quicker than the fuses. When switching, V th and its temperature coefficient is not relevant because the gate voltage is invariably selected to provide ‘hard’ switching to minimise losses.

Hi Harry as per following link it is a good performer. A basic dual power supply is used for the amplifier circuit. An example would work nicely here The large notch is at the second harmonic, and the small bump to the right is the fourth harmonic. As I powered up, Q5, Q6, and Q7 blew up.

What power will get when i connect 10inch 4ohm subwoofr? This is done in order to improve linearity and gain. Note that the two curves cross over, but the point where the temperature curves cross is when V GS is at a current of over 40A and the gate-source voltage is 5.

If one cell has a slightly lower V GS than the others perhaps due to microscopic variations in the silicon it will take more of the total current. There is not only one capacitance to deal with, but two one from the gate to source and the other from the gate to drain.

The amp works fine. Requests for component values will not be fulfilled. Better performance can be datasheett by using multiple LTPs, but this will not be a simple design in fact it will be quite complex with high frequency stability issues needing attention.

Irfp92440 graph was taken from the IRF data sheet, but has been colour coded to make identification of each graph easier. And remember one thing – any output device can be precise if a proper design is found.

That is why we need to buy a few extra and match them together. Does output of this circuit is short circuit protected? It is claimed to be ‘insignificant’, and for switching applications this is true. Normalising simply means that everything is taken back to a reference of unity, so simply multiply the claimed V th by the figure shown along the left side, for the temperature at which your device will operate.

The network comprising of capacitor C3 and resistor R19 improves high frequency stability and prevents the chance of oscillation. Make sure your measuring equipment is decently calibrated! The minimum stability network Zobel shown is always needed, and a series inductor with parallel resistor may also be required.

If things are ok set the current as recommended, and connect 8 ohms speaker and try. It will be great if I get your valuable suggetions. This application note also mentions the possibility of a failure mode similar to second breakdown when operating switching MOSFETs as linear amplifiers. The use of source resistors to help force current sharing is essential, and these should be as high as practicable.

There is no evidence datashee ‘notch’ distortion or any other datasheef odd harmonic, only a ‘nice’ second harmonic added in. This does not mean use an inadequate heatsink, but the bias between devices should be a bit more than many are used to. This amp will work, but you have to add a filter circuit at the input. 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.

This amplifier will burn.
