hi all

plz give me any circuit to convert 12V DC to 12V AC
i want to use in car
 

How 12V DC to 12V AC

salam ehsan joon
use inverter circuit or spwm.
regards
 

Re: How 12V DC to 12V AC

Well,basically oscillators are dc to ac converters only,but very high frequency.. So multivibrators and inverters will help..

This circuit converts 12v dc to 120v ac.. Try and adjust the transformer winding and get it to your required voltage..

For using gates(inverters) try this circuit.. h**p://www.interq.or.jp/japan/se-inoue/e_ckt8.htm
 

How 12V DC to 12V AC

salam be dostan gerami
it can made by LM3524 or LM3525 IC
 

Re: How 12V DC to 12V AC


all oscilator are nothing but DC to AC converters ( in this aspect, this view is acceptable).......

based on the shape of the AC waveform u can select the type of oscillator .... eg., astable multivibrator for pulse waveform , hartly or rc phaseshift oscilltor for sine wave ......

ok if i need sin wave 50 Hz then what to do
plz tell me as i m blank in the inverters
 

Re: How 12V DC to 12V AC

You can build a sinewave generator, some examples you can find here:

and then using an audio amplifier amplify this signal to 12Vrms (16.8Vpp) ..
Some amplifiers will give you amps of current at 12Vrms ..

anybody have any circuit or doc about spwm invertor?
 

Re: How 12V DC to 12V AC

You can use 12V DC as a power supply of a oscillator with desired frequency.
 

Re: How 12V DC to 12V AC

you can use inverter circuit to transform DC to AC voltage.
