Hi,
I am working on Square wave Inverter, after this i will go to sin wave using UC...
so, after completing Inverter using MOSFET and SG3524 PWM chip...
I want to know the procedure of feeding to transformer Center taped ....
I have generated the pwm as usual with adc and completed the mosfet driver with push pull to discharge mosfet gate capacitor quickly...
anyway, i need how to make wave of equal time period for feeding to both transformer...
#include <htc.h>
__CONFIG(LVP_OFF & BOREN_OFF & PWRTE_ON & WDTE_OFF & FOSC_HS);
#define _XTAL_FREQ 20000000
void main()
{
TRISB=0X00;
TRISA = 0xff ;
ADCON1=0b00000000;
ADCON0=0b10000001;//000 = channel 0, (RA0/AN0)
ADIF=0;
ADIE=1;
PEIE=1;
TRISC = 0 ;
PR2 = 0b11111001 ;
T2CON = 0b00000100 ;
CCP1CON = 0b00111100;
PORTC = 0 ;
while(1)
{
__delay_ms(10);
GO_DONE=1;
__delay_ms(10);
while(GO_DONE);
CCPR1L = ADRESH ;
}
}
How are the two lower transistors powered.??
From SG3524 it works on 12V...anyway i will post one more circuit later please you concentrate on uC PWM feeding rest i will manage..

You initially asked for help with the transformer driver,??
I have never needed and never used an inverter because I do not go camping and my electrical utility company provides very reliable electricity and the voltage regulation is very good.
