hi,
i have only posted the aspect of my schematics i think is related to the problem i have need to solve and that is, code to regulate the output of the inverter. i have the functional complete schematic.if the need arise i will post the full schematic.however for operational explanation,a single PWM signal is geenerated via the CCPR1L(RC1) of the 18f452,this signal is separed to PWM1 and PWM2 through the operational amplifier LM393 before passing to the steering logic of 74hc257 from where we get the four driving signals through the two unit (A/B) of the 74257.the additional signal on RC2(SWITCHING SIGNAL) is to change the input A/B of 74257.
i hope i make some meanings.can someone give a help to the regulation proble please?
