Thread starter MrNobody Start date Feb 27, I think I am getting there. The V[gs th ] needed is -5V.
Yes, you need to pull the source 10 or so V below the drain before it will switch fully on. Hero Banned Mar 4, I knew there was something I had missed. Thanks for your explanation. Haven’t tested it yet with 60V.
What’s the value of R1? MrNobody New Member Mar ir9f130, Initially, i do not really understand. Too much power loss and too little power reach the motor.
How about the VGSS.? Hero Banned Mar 5, Hero Banned Mar 16, Imagine the mosfet as a non-linear voltage controlled resistor. If you can get P-mosfets in the ratings you need, then just use them.
Couldn’t find the model that I am using in there. MrNobody New Xatasheet Mar 13, Should you have any questions Please don’t hesitate to contact me Via Email. When that happen, V S will continue to decrease because V D is the same. This happen when V GS is greater that 8V.? This way, when power datasjeet off, any noise or watever will not damage your motor, Or if the signal is somehow borken or not getting thru, the H-Bridge simply wont turn on.
The resistance R DS at that irc9130 would be somewhere near mOhm 0. Roff Well-Known Member Mar 15, Due to the lag in the Logic Gates.
Started by fastline Yesterday at 8: Here is a simulation of the H-Bridge circuit. How would I make the Source voltage become 20V.? That is the resistance of the motor measured with Ohmmeter.
The 2N transistors don’t have base resistors so the one with 12V between its base and its emitter is destroyed.
MrNobody New Member Mar 4, Does it means that my gate voltage cannot exceed -5V.? Generalx5 New Member Mar 9, This is the one I use because it has a fast Switching time, and low Gate Resistance. To participate you need to register. Yes, it would blow up datashet there is no resistance at the Gate. Yes, it would blow up if there is no resistance at the Gate So if you had an incomming signal that was either 1 or a 0, High or Low, only 1 N and 1 P type mosfet will turn on, thus if you refer to the diagram, the MOSFETS that turn on will be diagonal from each other.
H-Bridge DC motor driver. This is also very efficient because it also has no chance of shooting thru. I could be wrong – I was once before.
Is that what you mean hjames.? Correct – In order to use a n-mosfets on the high side, you need to supply a gate voltage that is greater than the supply voltage that it is switching – since you want Vs of the mosfet to be very close to the supply voltage. I would also stay away from PWM signaling. Hero Banned Mar 15, Forums New posts Search forums. Also for better reliability.
When you say “source flowing at about 5 to 10V”. Media New media New comments Search media. According to the simulation, the V DS of Q1 and Q4 is too large and only less than half of the voltage fall across R1.
