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

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

If you had the schematic diagram for a 15KVA inverter magically fallen from the sky to your hands; it is very probable you would never be able to build one.
The parts are not at the corner store.
And from 12VDC it would suck up to 1500 Amperes from the battery. Do you have an idea what 1500 Amperes mean ? :cry:

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

hi, i know this topic well. i am making an inverter for 120V AC (rms). you must choose a topology first. i would suggest a Full H-Bridge because of its current carrying capability.
then you must create PWM switching for the elements. the switching elements should be MOSFETS at power levels of 500W or less. BJTs are for less than 1A projects

I want to test 2 different types of piezo actor.
For the one i need a voltage of -45V/125V for the others i need a voltage of -100/350V.
to switch the piezo between the negative and positive voltage levels i think the best solution is to use a h-bridge.
Did somebody have a useful design for the inverter and for the h-bridge?

First look for signs of passive part failures which usually overheat and change color. The most likely failure is the transistors. If you do not have a method of testing them, it is usually best to replace them and see if the inverter works.
