I have designed three phase inverter in ltspice with SPWM technique using mosfet switch. the output voltage at the load is incorrect. could anyone please tell me what is wrong in the simulation to get the output properly.
In this circuit im trying to calculate the inductor value required to get a frequency cut off of 4khz, how do i go about this? I cant seem to get an equation as i cant use the basic passive equations since R2 is not in its 'normal place'.
So I am interested in the charging of NiMH batteries, some websites say that they should not be charged over 0.1C, some say 0.5C some say not over 1C.
I bought this wind up torch with a 80mah 3.6v batteries pack and noticed the current flow is around 200 mA, this is 2.5C.
I have a question about LTspice for power electronics.
how can I plot a parameter along the full simulation time, but it is averaged for each switching period?
That is to say, Can I see this averaged value changes along the time?
I know the .meas command can integrate between the...
I need a good understanding of the attached rectifier circuit.
Requesting all experts to explain how it works, its function and advantage and disadvantage as well.
Guide me for further development, how could we modify it.
This system contains 3phase, 380V, 50Hz ac input...
hello guys ,
Here is the situation, I am working on a 90 watts , 1050 mA , 72 V flyback based constant current smps which is used for outdoor LED lights,
Mosfet used 12A 800V
O/P diode used - Average forward current 8 A , Peak revers voltage 400V
In this design diode and Mosfet are getting...
Some opto-couplers, like 4N25, have a terminal for the base of the output device, what are the advantages of having this terminal? Looking for an answer, I ran into this. I can somehow understand that the base connection can increase the speed but I don't understand how this terminal can be...
I am working on a project and have to design a common gate amplifier by using MOSFET so I am a little bit confused in desgining can u help me the circuit designing of common gate.
I just want some parameters value like resistor at gate and drain and source plz help me
