    Inverter Circuit 12V DC to 230VAC Sine Wave

    I c....but the reason that i use RC filter is because i used the connected load as R. Rload = R filter. Assume that i am using LC filter, what will be the low pass cut off frequency that i should set? is it 50Hz? If so, i set the C = 1000pF then, the L value will be very large,right?

    Inverter Circuit 12V DC to 230VAC Sine Wave

    Thanks audioguru  :) Now i have increase the PWM frequency to 19kHz.  But my inverter design at the output there is a bit different. I use ADC to convert a single phase sinewave with peak amplitude of 5V to PWM signals. Then, the PWM is used to switch or chop the 220Vdc. The output that i...

    Inverter Circuit 12V DC to 230VAC Sine Wave

    Hi there everyone :) I have constructed the H-bridge circuits which is control by PWM, the frequency of PWM is about 4900Hz. Therefore, a single phase PWM sinewave at 220Vrms is generated. Then, my questions are how can i filter this 220Vrms PWM sinewave into a perfect sinewave? Should I...

    Inverter Circuit 12V DC to 230VAC Sine Wave

    Hi there, does anyone know how to convert the different width pulses(vertical) of a PWM signal to different height pulses(horizontal) accordingly....any comparator I C can do this ??? Thanks. ;D

    Inverter Circuit 12V DC to 230VAC Sine Wave

    I c :o...thanks....but is there any low cost but effective ways to convert a 12VDC to 220VDC? Hi,kachew....at the moment i still on thinking...so,i still not certain with this design yet... :-*

    Inverter Circuit 12V DC to 230VAC Sine Wave

    ;DHi,audioguru: what i found is the ferroresonant transformer provides squarewave output but just require less filtering...... if i use PWM method  to convert a low VDC to high VDC through a ferro transformer. Then using H-bridge (which is switch by PWM) to chop the high VDC to obtain 240VAC...

    Inverter Circuit 12V DC to 230VAC Sine Wave

    Hi,audioguru :) i'm interested in constructing a pure sinewave inverter. Do u know any books that talk about how to design this kind of inverter? the ferro-resonant transformer that u mean is it same as the ferromagnetic transformer ???
