    12 V DC to a 220V AC Inverter AMplfier Design

    no no... i dint mean that....i mean how much mosfet will draw current from the battery? and what is the desired output Amps at the output of the trans? how we can determine the output amps....as i know the amps is dependent on how much load we have in the circuit..... any calculation can prove...

    12 V DC to a 220V AC Inverter AMplfier Design

    dear AU, from your explaination i know abit of transformer thanks...but how can i know or make the output to have desire voltage regulation? but putting the desired  value of resistor at the drain of the mosfet there? can u prove it by calculation so i can have better understanding on the...

    12 V DC to a 220V AC Inverter AMplfier Design

    hi Au, how can i know how much currents flows in my circuit? izzit the same amount of current as shown in the datasheet for the mosfet? how many amps of current will flow to the transformer and what is the output amps and voltage as the modified sine wave circuit is recommeded by you....isnt...

    12 V DC to a 220V AC Inverter AMplfier Design

    dear Au, i did the corrected version but still no avail, mayb the IC hav destroyed by me... cos i have wrongly connected the supply to the pin 13.... will it burn the ic? i will try with new IC of CD4047 to retry.... is there any other compatible IC can be used to replace this function generator...

    12 V DC to a 220V AC Inverter AMplfier Design

    dear Au, ooo mayb i did wrong already....i was been told by my fren on how to connect the probe...mayb because of this the ic burned...i try to buy a new cd 4047 and try to redo.... here i reattach the file....so u can check for me..... thanks Au

    12 V DC to a 220V AC Inverter AMplfier Design

    hi all, i have tried the CD 4047 and i cant get the desired output from the Oscilloscope....can anyone pls help me? i cant get the square wave pulse from it....i have connected a +12V supply  and ground (which is connected to -VE supply with a wire) from a DC power supply at my lab. i have...

    Inverter Circuit 12V DC to 230VAC Sine Wave

    hi guyz, just wants to ask u guyz how to increase the voltage if i'm using mosfet and center tap tranformer to make the modified sine wave inverter? cos currently i notice that my transformer needed is too bulky....i need to make the inverter portable...thanks for u guyz help.... ;) ;) ;)

    12 V DC to a 220V AC Inverter AMplfier Design

    hi audioguru, may i know the transition of the pulse where both mosfet are turned off? you only shows the transition where 1st and second mosfet are turned on....and i would also like to ask why we want to use the drain source of the mosfet to ground the center tap transformer? thanks for your...

    12 V DC to a 220V AC Inverter AMplfier Design

    hi audioguru, i think i know what is kachew tryin to deliver.... ;D the concept can be found in any power electronics book ;D ;D and i also attach a circuit i think is similar to your concept using the cd 4001....and audioguru can u try to explain your circuit using the cd 4001 and mosfet as a...

    12 V DC to a 220V AC Inverter AMplfier Design

    hi audioguru, then what u means is the mosfet will only produce only 2V from each mosfet to the transformer so the is unactive in this circuit? then the previous kachew inverter is theoritical working (exclude latest modification) and the mosfet is acts as a switch?? and for 200w output the...

    12 V DC to a 220V AC Inverter AMplfier Design

    hi audioguru, i think there is some problem due to the circuit....i think the CD4047 and CD4001 can be act as the control circuit for the swithing circuit which must consist of four mosfet in order to get the modified sine wave?? in the 1st cycle the signal from the control circuit will go...

    relay question

    dear MP, then what you means is when we want to use relay for 12V circuit with power rating of 200W, the we should choose relay rating of 12V and 20A? because 200/12V?? thanks for your reply
