    Sine wave Inverter Project

    So can we make multiple cascaded Class D amplfier IC you suggested and make it  upto 1000W or the Class D amplfier i gave , can we ???

    Frequency Generator - 2 Fixed O/P

    The IC XR2206 By Exar is a very neat IC and can produce generate sine , square , sawtooth , pulse and triangle waves , up to 1Mhz And above . It can also Modulate FM and AM signals. you can use it's datasheet , to find the circuit diagrams . it's fairly simple to tackle with the frequency and...

    Stereo Audio power amplifier 2 x 40W - 80W

    I found a commercial audio power amplfier and i have just finished it's PCB mapping . although some parts need a little image enhancement. because some connection were broken when i mapped the PCB. When i am finished i will place the corrected PCB , and details, also the preamplfier module. so...

    Transformer Power Rating

    ok then i am preparing to add something else , temprature meter , fan , and a Power meter that shows the actual wattage, for power measurment i will be using  a ADC to measure voltage and current and then when it is binary form , digitaly multiply them using logic gates , and then convert the...

    Led display Digital Voltmeter question

    The PCB artwork and layout , sorry for too many jumpers. but the thing is this panel meter was for something else then measuring voltage , i am actually calculating length from it . i will post the full project when it is complete

    Led display Digital Voltmeter question

    Okay this is not a theory discusssion , i have built the ICL7107 voltmeter and is working great , form www.electronics-diy.com , here is the PCB layout and silkscreen. the lines are jumpers These are the componenets list VALUE        SHAPE        #    REFDES      1.0MOhm_5%  R0204R7_5   ...

    Transformer Power Rating

    I have a Transformer capable of delevering 8A @  2 x 28V . and one more thing , i could not found P600B , can i use a simple 1000V @ 6A diodes that i can find , i don't have the exact number , but i will if i buy it

    Sine wave Inverter Project

    I mean to say the output from the transformer that is square wave. and it is shaped to sine wave

    Sine wave Inverter Project

    hmm i think probably it would be nice to use a bigger 12V battery and use a DC-DC Converter

    Sine wave Inverter Project

    please take a look at the link i posted above , i think it is a simple and effective design. but i can't find how much power it is delivering

    Sine wave Inverter Project

    Since Class D Ampilifiers are cold amps or have 100% theoratical efficiency with upto 94% practical efficiency . it is very much suitable for a sine wave inverter design , however i was able to look up a site which is open source class D Amplfier Site http://hem.passagen.se/johanps/index.htm...

    Transformer Power Rating

    Well i have all the transistors , diode and i felt lucky in getting the exact Darlington pair both are from texas instruments and are BDW84D and BDW83D respectively so now how will it behave , how much watt  ???
