your saying about clarity...its way beyond dude....i get a huge short accros the series....when i connect fets dont know why...can u plz help me out
everything is ok the waveform on high is small in size than the low side.....comparable 3 times small i guess
Nonsense, it wouldnt work at all.
Look at the slew rates:
lm324: 0.4V/us
tl074: 15V/us
Lm wouldnt oscilate.

If you are using lm's? Thats probably the reason your fets are smoking. 😉
gr8 thanks buddy.....but are u definite with ur opinion....and what would be the other reason if this aint be the prob
hi guys. the hi power version in bridge mode. i will upload artwork later 😉 😉

hi all i made bridged version and tested it but . when i pushed it hard with a 6ohm load that is a 18inch woofer the amp failed after 2 minitues. .i think my tracks for pcb were small the ones feeding the output fets. also
>>> btw the circled components were heating above normal.
here are the photos

Use resistive load for testing...don't you care about your speakers and your ears?😀.
Also any amplifier must survive continuous rms power into resistive load to be reliable with music😎.

No,the opposite is correct😀.
A speaker is a non resistive load, in fact it is a nonliniar inductive/capacitive/resistive system depending on its configuration(single or multiple in cabinet and with or without filters).
stewin:
Power resistors with their resistance smaller than rated impedance, example: for 4 ohm impedance use 3 or even better 2.5 ohm low inductance resistors or resistor network

You simply draw the schematgic, assuming multisim has models for the components used, which as far as i know it should.
ni multisim doesnt hav models for ir2110 or irs2092. i hav seen several class d schematics with these two componets but i dont knw which cad was used. can anyone cum to my rescue please.
The schematic post 246 showing bridged class D may experience problem. Both halves may oscillate at different frequencies and some intermodulation product may be heard.
Bridge class D amp should be done using the same modulator or synchronized modulator.
