    Editing of TRAN 2P2S Properties

    Hi Am trying to step down a 240V to 12V with TRAN 2P2S in proteus. How should I edit the properties 'Primary Inductance, Secondary Inductance, Coupling Factor, Primary DC resistance and Secondary DC resistance' values to obtain the require 12V at the secondary. Am doing design in Proteus...

    Codes for ADC on PIC16F877

    Hi Jayant, This is how I want my system to work. The load is supplied by utility at 240V 50Hz. When utility goes off I want to automatically detect it using the MCU, then start the gen set automatically and then hook the load onto gen set. Pls any suggestions! - - - Updated - - - Hi Kabeer am...

    Microcontroller based automatic transfer switch

    Hello! am trying to connect three optoisolators as voltage sensors to a PIC16F877 MCU. I've built the optoiso circuit with 47k resistor and 1 diode. The output of the optoiso oscillates between 0-5V. How do I interface it to the PIC16F877. Do I just connect it to the MCU's ADC pins? Urgent help...
