lattice programming cable
Ok, there seems to be a little misunderstanding: i want to use the parallel port to program a Lattice CPLD. So instead of buying the 70$ or more cable i want to use the schematic that is in the file that i attached or the one that FvM uploaded.
Pls dont give me the...
latice cpld programming cable
The USB cable arrives here for about 240euros from 160 or so $. You can imagine how much the 70$ parallel one will be.
I want to make it as low-cost as possible and will try to make it with the adapter for the Sun Workstation(page 2 from the file that i attached).
dlc9g adapter
Hello,
can anyone help me to program a CPLD from Lattice(the ispMACH4032V and 4064V). I would not want to purchase the ispDownload cables from them but rather make a small adaptation to programm the device with a parallel port.
After some searching i read that it can be done using...
I want to use these drivers for an H bridge but havent figured how to properly connect them so that they work.
Here is the part of the schematic that includes them:
**broken link removed**
As this,when i put all of this on a test board it does not move a bit.
The upper mosfets should switch at...
Transformer wire size
I need some help in choosing the right wire size for a push-pull transformer that has 12v(min of 9 ,max of 18) input and 350v output.
The Ae=76mm^2,and it is working at a switching freq of 100kHz.From the design i understand that the output is working at 200kHz.
175W...
design of push pull converter transformer
I need a little help on designing a transformer for my push-pull converter.
The input voltage is from 9 to 18v,output should be 350v,operating frequency 100KHz,output current 0.2A and the core should be a ferrite one.
The push-pull is a center tapped...
ir2110 dc-ac inverter
Thats a start,but i forgot to mention that the transformer@50Hz is a big no-no for me.
The schematic should look something like this:
12vdc then a push-pull then a h-bridge -->230v ac
The command circuitry for the push-pull mosfets and h-bridge should be a 3846...
I want to build a dc-ac inverter with the following specs:
12v input
230v output
100W
2x IR2110 for the H-bridge mosfets
3846 for a half-bridge push-pull
and a uC to control the PWM for the H-bridge.
The output should be a pure sine wave.
My questions:
How does the IR2110 work.What kind of...
