I have a motor contro board with a fault tolerant control, and we have used current sense on each one of the three phase of the brushless motor.
The sensor are LEM LTSR series, and they works perfectly, as they are closed loop hall-effect sensors.
Now we want to reduce sizes (and costs) of the...
Thanks for your replies, they are very confortable :-)
My idea is to use the L6562 from STmicro, because with it I can implement a FOT (fixed off time) for having a variable frequency and then less EMI.
Orson, could you tell (if it is possible) some information about your design?
For example...
Hello,
I want some advice about this kind of architecture: it is possible to design a PFC which works after a mains transormer?
My ideas is to have a toroidal transformer 230/48, which solves my problem of having a 5kV input/output isolation, then I want to put a PFC, and then stuff like DCDC...
Arduino:
www.arduino.cc
en.wikipedia.org/wiki/Arduino
it is like a development board, wich provide easy access to uP interfaces, expecially for whom are not experienced in hardware electronics (soldering and making circuits), and want to develop software quickly. A lot of university use it in...
I am checking it, there you can find people looking for libraries.
But my question is a bit more "conceptual" of finding a single library of a components:
If I'll start a big porject, with dozens of components not included in orcad standard libraries, Do I have to spend all days googoling for...
If you like processor programming you can choose:
- arduino (university level uP)
- PIC (industrial grade uP)
I used the pic18f45k20, and with a small fee you can buy the demo board with 10 pdf lesson files.
it is easy to start, and you can make funny things!
the smallest demo board is **broken...
mybe I can not give a full answer, but you can have a look of what other uP do.
For example, if you look at a PIC18f45k20, at page 253, there are the AUTO-BAUD detect for the onboard EUSART.
Hi everyone,
I am using Orcad 16.3 for a project of a industrial PCB. My company gives me an Orcad schematics, already well done by external engineers.
In this schematics there are a lot of components which are not included in my libraries, such as uP, RS422 trancievers, Maxim encoder...
