hi,
this is software code for that...
Gate drive signal generate on Singal PIN (PORTA_PIN0)

unsigned short sync_time,alpha;
void PWM_module_init(void){ //initilization of PWM module

PWM_module_ch0 //config as input capture& both rising and falling edge interrupt Enable
PWM_module_ch1 //Output compare1
PWM_Module_ch2 //output compare2
Module_counter =0xFFFF; // free running
PWM_module_freq // 4MHz
}

void Input_capture_interrupt (void) {
clear flag;
sync_time =input_capture_count;
Output compare1 = sync_time + alpha; //[alpha = 0 to 40,000 counter value]
}
void Output_Compare1_interrupt(void) {
clear flag;
PortA_pin0 = 1; //send higt to port A pin 0
Output compare2 = sync_time + 40000; //[40,000 count = 10mS]
}

void Output_Compare2_interrupt(void) {
clear flag;
PortA_pin0 = 0; //send low to port A pin 0
Start_ADC;
}

void ADC_interrupt(void){

stop_ADC;
alpha=ADC_conversion_data; // 0-3.3V => 0-40,000;
}

i am getting almost perfect output but synchronization problem..
alpha is varying between 0-180'(0-10mS)
