Hello! I want to buy a MOSFET in the rating of 600V/20A. I also want to buy MOSFET driver for that. I have to use it with Arduino Uno for controlling purpose. But I can't select which one to buy. Can anyone suggest me a good MOSFET + MOSFET Driver?
Tell us about your project. Do you want to control a motor ? Do you want to use PWM ? A PWM signal at what frequency ? With a H-Bridge ?
For higher voltages a IGBT transistor is sometimes used. Perhaps a complete IGBT module is the best solution for you.
Do you know how to deal with such high voltages and high currents ? Have you done that before or is there someone that can check the safety ?
I want to control a motor with two pwm signals from arduino. One of them is complementary pwm. The frequency range is 40 to 4000 Hz. And I never done this before. So suggest me something for it sir. I'll help us a lot.
That's a half-bridge. For that a half-bridge driver chip would be used, and the good ones have shoot-through prevention logic (you really want this). Some generate the complementary signal for you too. There are far far too many such chips and MOSFETs out there to pick "a good MOSFET + driver" - you need to know your requirements first.
Most good electronics components stockists have search engines for finding parts matching specifications for you.
Start small, low currents, low voltages, and build up, for there's a 99+% chance if you dive in with high power/voltage on your first attempt you'll simply blow up your MOSFETs and driver instantly.
Good test equipment is needed really - without a reasonable fast 'scope you'll be working blind and its tricky enough to design high power bridges successfully with one...
In general it might be easier to find a suitable motor driver that's got all the protection circuitry and is a known performer. Though if your intention is to learn, as I said start small. Build up your experience first.
Hi,
Why complementary, use Full H-Bridge.
40 to 4000Hz can you explain why you need to vary the frequency?
Do you need to change direction and speed?
