Hello everybody. I need some sort of variable frequency astable to drive a total of 12 mosfets (2 sets of 6 mosfets each). I use them as switches. Only one set at a time must be on. Indeed this can be acomplished with a classical astable, however I would like to have a delay between the two on times.
So I would like to have the following in sequence:
1. Set 1 (6 mosfets) turn on then off
2. Small delay (to compensate for mosfet turn off time)
3. Set 2 (6 mosfets) turn on then off
4. Small delay (to compensate for mosfet turn off time)
5. Repeat
The reason for the delay is to avoid a short, between the td(off) and td(on) among the two sets creating a shoot-through condition.
The mosfet is irf8010pbf.
When the mosfets switch, I want them fully on just like a physical switch. The mosfets will swich Vds 50V through a relatively small resistance. (I will implement cooling method if needed)
I will supply any voltage necessary for this driver. Idealy the frequency range of the driver shoud be very wide from as low as possible to the limit of mosfet switching or driver capability.
What is the most power effective solution? Or any solution for that matter.
