    12 V DC to a 220V AC Inverter AMplfier Design

    dear audioguru, so the rest of the part is ok already? for the ouput in order to get lesser like 200W i shall reduce the mosfet or change the transformer value???

    12 V DC to a 220V AC Inverter AMplfier Design

    dear audioguru, if i wanted to make and modified sinewave inverter with a single mosfet as you recommended which power mosfet can u recommen me? cos i weak in looking the datasheet...so audioguru can u teach me how to calculate the loss in the mosfet so i would know the power rating used for...

    12 V DC to a 220V AC Inverter AMplfier Design

    dear audioguru, as u can see in the sasi inverter circuit it also uses CD 4047 but there sasi uses 4.7k not 47ohms and may i know what is the use of the capacitor and resistor near the transformer ?? thanks

    12 V DC to a 220V AC Inverter AMplfier Design

    dear audioguru, 1.can i still use the transformer u recommended earlier ???(8.5-0-8.5) 2. so for my circuit do i need to add the LM358 or straight use the CD4047?? 3. in font of the power mosfet i still need to put 1k resistor? if i use low on resistance???

    12 V DC to a 220V AC Inverter AMplfier Design

    dear audiouru, may i know wat is the power rating for the transfomer???is it usin the equation p=vi? is so in order to get 150w at output 220v then we need 0.68A and at the input then we must have at least 12.5v? tought u said this to me before??? why call me to use the LM358 again??? or do...

    12 V DC to a 220V AC Inverter AMplfier Design

    dear audioguru, is it the 396us is the operation cycle for the mosfet?? so its take to 396us to amplified the voltage in the 1st mosfet in the positive cycle and the same time to amplified the negative cycle in the 2nd mosfet...so is it u mean that the resistor in the gate mosfet the larger the...

    12 V DC to a 220V AC Inverter AMplfier Design

    hi audioguru, i just wan to know the use which pin to connect to the pin Q and inverted Q of cd 4047? :'( :'( and how about i add LM358 amplifier to increase the output current from the CD4047 in order to increase the efficiency? ??? ???

    12 V DC to a 220V AC Inverter AMplfier Design

    dear audioguru can u show or tell me how can i connect it to be modified sine wave?? can i use the circuit i posted here http://www.electronics-lab.com/forum/index.php?topic=1360.112 to change from sine wave to modified sine wave inverter? cos i wan to use mosfet than transistor to increase the...
