Hello everyone,
I'm in research of a device for a project I'm working on, and I would like to have your opinion if it's possible. The purpose is to drive 4 mosfets of a full bridge inverter.
Of course there are a lot of devices that can do this, either using counters or by digital outputs, but I would like to find a cheap one that meets my specifications so that my department's Labaratory could buy it and have it for future work instead of borrowing it from NI for a small period.
So, what are my needs more or less:
I want to produce 4 high frequency train-pulses (>=100Hz). As far as I know the frequency is not a problem meaning that most of the devices can produce digital pulses of such frequency levels. Another important thing is that i want to synchronize the 4 train pulses and also to insert delays so that i can vary the duty cycle of the inverter's output voltage.
So the question is.. what would be a cheap solution for the purpose descrived above?
During the previous semester I used the X-Series USB 6351 multifunctional DAQ device and it was very convenient using the 4 counters but i had to return it back.
p.s Is it by far more complicate to create configurable/sychronized train-pulses using digital outputs compared to counters, or it's just me? I'm asking because if this is the case I would prefer to have a device with 4 counters again and make my life easier 🙂
Thanks in advance for your time
