...seems like we are coming all to a similar path for the gate drive...

Send PCB to me ego_akai@163.com
Thk. very much

Mine 2KW using 4 X IRFP4227 in full bridge mode, single supply and common inductor. SWF=325KHZ. IR2110 used with buffered drivers from Zetex.

Performance measurements?

What modulation you are using, AD / BD ??

AD using Post filter feedback

Hi Workhorse

Looks great.
Where are the output mos? (don't see any through holes ...) .....
Do we get to see the other side of the PCB?

Why do you opt for full bridge? Seem to remember your last design shown here was a half bridge with +-200VDC PSU ...... so why the change in topology?

Kind regards Baldin

Hi Baldin,

Cant you see 4 holes between output inductor and 2 black electrolytics?

I wanted to TRY my hands on fullbridge also i did it

The access to otherside of pcb is restricted

What you should had say is that people in your country has no money to afford current great high-efficiency amplifiers (and I don't talk only for Romania, everywhere is the same).

But if someone come in the market with a SMPS + Class D amp at 2x3000W RMS 2ohm at 10kg and with the same price than the current Chinese mammoths (and it's possible), people will start to buy class D ! no doubt about it...

You don't think so ?

Hello Mr.ArthurG

some romanian people in the audio domain are very interesting:
- they tend to think that they know everything and so they paralel speakers on outputs, place more caps in order to obtain more power and so on.
- they try to copy everithing they think that can be copied.
- they try to fix broken amps with lower quality components to make more profit.

so in this case a class D amp is off limits because of the PCB design, lack of know how, lack of 100Mhz scopes, lack of patience in learning and accepting that they may be wrong.

not all are the same. but the ones that realy do know what a SMPS and a Class D amp means rarely share info.

Regards,

I would tend to say that this and probably also most of your previous statement is valid globally, not just romania.
