I am using this circuit. As DC bus I am applying currently 30V and at output I am able to achieve a sine wave by further employing a filter Circuit In theory what should be the peak output voltage of the sine wave???? Shouldn't it be +30V I am getting a peak of +12.5V and 25V p-p. Hi Who told that out put voltage must be as VDC ?
Keep in mind the source impedance out of your inverter is N squared times your input source impedance, and you want this as low as possible for good load regulation. ( Source/Load determines error) Using a centre tap 12Vdc to 220Vac you have 220Vac/24Vdc or a turns ratio near 10:1 with a centre tap. So output impedance will be at least 100x b
Your induction motor SHOULD have a label; how do you even know it's an induction motor? In theory, the switching frequency of the inverter should be irrelevant since it will be filtered out and all that appears on the output is a pure sinewave. Obviously this is not reality. If it were me, I'd look at the waveforms across the motor as you vary
In theory, with ideal devices, your circuit wouldn't do anything since the inputs to the AND gate are never high simultaneously. In reality, your circuit will output a narrow pulse on the low-to high transition of the input with width approximately equal to the propagation delay of the inverter. Is that what you intended?
What type of "inverters" are you interested in?
See this like starting idea It will hardly implement the 50/60 Hz frequency conversion. Generally speaking, the hardware of a typical single phase motor inverter is what you need: Input rectifier, bus capacitor, PWM controlled H-bridge, output inductor, possibly a sine filter. If high input power factor is required, the AC/
Is there any dependence of Vth (CMOS inverter) on Temperature in 180nm technology? If so wat relation can be given between ?n and ?p?

You can look other threads about ups/inverters in this forum just in search field type inverter or ups. There is lots of circuits and theory.
How logic gates are made should be part of microelectronics course. The course you mentioned, should be based on device( and above) abstraction- means it should be considering the MOS as switch. I can't be sure, but the course should include following: 1) What is MOS and how it works? 2) Basic inverter from MOS. 3) Basic gates from MOS. If you ca
In theory, CMOS inverter consumes zero static power. What does this means?????
freeman At least to me, still is not clear if you are concerning to control PF at input of SMPS, or to control PF at output of inverter. +++
Hi all, I am designing a inverter in 0.25u tsmc tecnology. when i am doing transient simulating i am gatting spike. VDD=2.5V. spike around 0.1v. even the DC characteristic is perfect. Thanks & Regards Anand
Hi All, Please Help me with my project (Final year Engineering project) and it's about Multilevel inverter (theory and Application) Please if there is anyone know anything or have any e-books about the subject please help me.
It is not the design task to have the Vth of the inverter in the middle of the supply voltage. The prior task is to guarantee symetric rise and fall times. So the dynamic is of more interst than the static case. A symetric static (dc) transferfunction differs from symetric rise and fall times since there are different input caps to load for p a
