My class D amp

[endryc1]

This is the PCB mounted on the amplifier in the first photo.

 

[lutkas]

good one, I will tryit too

Hi hadi,

This is my last project. I didn't test right now

AUD600i is Sigma delta with external osc.

Hi, what is switching frequency ?

I think high Voltage gave high switching losses and hot core

 

[norazmi]

he not build yet

Hi, what is switching frequency ?

Hi,

Yes it is very high volt design and care should be taken

Planing to set 350KHz or 380KHz.

Hi,

yes.Waiting TLP2270 & MOSFET and before making PCB i want to check again any mistake in my circuit

QSC using 500V Mosfet in PL380, Halfbridge, 250 khz FSW

Rail 160 V DC

You will have High Switching losses in IDLE with 180 V DC

Amp is much more warm in IDLE with this high Voltage v/s Class H / TD / EEEngine Amp


I think its better to have max. 125 V DC and Fullbridge

The amp will work, its Basic Standard Design like D4K5 + TLP2270, but SAFE ?

IR need Buffer like D4K5 oherwise get hot

This is my opinion, lets try

Hello all class d gurus, im new in diy auido...
Can u pls help me to find igbt....500volt 100amper
Please help me...

 

[norazmi]

go for fullbridge is better

 

[manojtm]

I think its better to have max. 125 V DC and Fullbridge

Hi NMOS,

You said right full-bridge(+/-95V) is better than Half bridge +/-180V supply rail.

Hi sneha,
not good for class D amp

Hello sir, you said not good for class d but i saw some amp.used 160 vdc in amp and works good...

 

[manojtm]

Hi sandeep,

IGBT is not fast it's for lower fsw{below 200KHz} only( basically for SUB application)

Hi manojtm. I have one question for you. The regulator used in aud600 amp based in mosfet and tl431 is suitable for +-100v amp .I am using this regulator and protection for my amps. Thanks a lot.

Hi All good morning.
Why this thread is in silent mode.Any progress I want gate driver si8244 based d class ampl .circuit please help me.
Thanks
