Hi Mr. manoj,
I have a question about the inverter IC,
Is there any special purpose to use 3 inverters on serial mode before feed it to the
HIN of IC IRS2110 (Picture 1)?
What happen if we only use 1 inverter each before feed it to HIN and LIN of IC IRS2110 ( Picture 2) ?

Warm Reagards

I don't know if some one has ask about this before if its please forgive me.

I try to build class D based from IRS2092 but I can not find toroid T130-2 for LPF locally and I think to use ET49 from old TV PSU yes I have an LCR meter to wind the coil to value I need but I not sure about use gap or not gapping for this purposes. can some one shed a light to me in LPF must I use a gap or its must be gapless ?

thank You
 
Hai manoj sir ,
I droped your 250sf due to the presence of smd parts, cos am not gud at SMD & dont have soldering station for it. So once again am going to explain my need, sorry for that.

1. I need an Amplifier for SUBWOOFER. But right now am confused in selection of subwoofer. Do i need 4R or 8R subWoofer which is ment for Home. But am certain about the wattage & size ie, 250W 12". Please can you help me.

2. For this which Amplifier should i use.
