Hi,
Thank you very much for the suggestions. The problem was exactly as what you told. One of the ADC pin( assigned as digital i/p,, not as adc ) has 0.7V more than the Vcc. When i removed that connection everything became alright
Once again Thank you very much for the much needed Help.

Hi
1. You can select MOSFETs according to the voltage & current ratings, Also consider the Rds(ON) .. use least RDS(on) MOSFET so that heating will be less.
2. You can use N channel mosfets at High side , but to drive high side gate you have to use boot-strapping or separate isolated power...

PIC 16F887 TQFP 44-pin package ADC problem.
As i have been working with the PIC 16F887 TQFP package we encountered the following problem with ADC and concluded the following results:
1. We infer that the ADC channel assigned while reading goes high (@5V) and remains high until the ADC channel...
circuit diagram for inverter
visit microchip "reference design 2" on www.microchip.com
its a valuable one. itis giving the circuit diagram and full code
u are using the differance of timer1 values between two consecutive interrupts.. what will happen if ac has failed (no interrupt has come) for next 10 or 20ms..
u have to add a timer here and do the change over from ac mains mode to inverter mode if the interrupt has not come for the specified...
Hello please , produce a 100Hz square wave from ac mains supply( after full wave rectifiaction of 50Hz sine wave) . and feed to PIC. if it is absent u can sense that the ac mains is failed
