100vdc Mosfet H-Bridge w/Drivers

Started by mr0x1001001 April 18, 2004
Hi,

Anyone have a reference design or pcb layout (Eagle pref.) for
an 100vdc MOSFET H-Bridge w/drivers? I have ir2110 and 300vMOSFETS,
but am open for others.

Cheers



As far as I know there are no bridge controllers that can work up to 100V.
The HIP series can do 80V.
Have a look at <www.irf.com>, they have some hi-side drivers that could
do the tricky part of the job.
It is also quite simple to do it all with discrete components but it tend to be a
bit messy...3-4-5 driver transistors per. output transistor.

Mr. 45...what do you plan on driving with this bridge?

45? :)

Robertv!


I'll be driving a 90v DC brushed motor. I have the IR2113 drivers and
some power mosfets, but have not wired them up yet. I also have the
IXYS IX6R11 driver on the way. ( wanted to try both ) I guess
discreets is the way to go.

I'll be using 2 sided PCB to build the Hbridge, so I hope the traces
will handle current draw. (50a peeks) Also, I think the IR2113's
need PWM on 3 of the 4 gates/mosfets to keep the bootstrap charged.
The layout in the IR appnotes is wrong. ( fig.10 ) The gnd and v+ is
shorted in the layout, and the support guy at IR says it's
just 'pictorial'... I was hoping to find a schematic/layout for
either the IR or IXYS drivers/mosfet h-bridge to confirm things are
hooked up correctly.

Thanks for your help,
Mr71

Maybe bridge not, but definitely 4 mosfets yes.
Like the N IRF530 100V/14A and perhaps the P part.
Of course some basic electronic skills are required.... :)

top 10 wishes,

The thing is I'm still confused as he later called himself Mr71.
I know binary was never my strongest point but what the hell!

Rv!
