Designing Audio Amplifier with BJT and MOSFET Components

AI Thread Summary
The discussion focuses on designing an audio amplifier using both BJT and MOSFET components, specifically seeking a schematic for a Class AB, D, G, or T amplifier. The user mentions a powerful 5000W amplifier utilizing 2SC5200 and IRFP250 transistors, powered by dual voltage supplies. They express interest in amplifiers that operate with switching technology and complementary configurations. The user has found various resources online but is looking for specific power amplifier schematics that incorporate both BJT and MOSFET components. The conversation highlights the need for clarity on the role of an IC in controlling the switching operation within these amplifiers.

Hi, I'm new here. can somebody put here an a schematic of Class AB, D,G or T. I need an audio amplifier that work with bjt and mosfet simultaneously, i think that kind of amplifier is class g, but I'm not sure,for example i saw an 5000w amplifier with 2sc5200 and his pnp pair working with irfp250 with his pair, the power supply was 80V -0- 80V and 70V-0-70V.
That amplifier works with switching, i think.

Thanks for your help

P.D: my english isn't well Sorry I'm learning

What kind of audio websites have you tried looking through so far? I googled audio amp tutorial power schematic, and got lots of hits:

For example, here's a website with links to lots of pages with schematics:

And here's a book resource from Amazon that you might want to check out:

Thanks for your help, but i need specially schematics of Power amplifiers, my need is an schematic of some amplifier that work with switching with mosfets an Bjt, better if is complementary.

i will check that links.

Thanks
 
i saw one amplifier with this system, with an a IC, the reference i don't know, one comrade said that this is an a regulator, or can be a pulse modulator, i think what that IC control the switching operation with the mosfets and Bjt's


My english Sucks!
 
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
