555 DC AC inverter

  1. May 29, 2006 #1
    How are you EEs. I would like to use my 12V car battery as backup power for a 72W television so that I can watch every minute of 2006 soccer world cup action (in case of Electricity company power cuts).

    After some searches I found this inverter http://www.uoguelph.ca/~antoon/circ/555dcac.html [Broken]

    I intend to build this or another simpler and cheaper inverter
    But I have the following questions
    1)What is the power rating of this inverter, is it suitable for my TV.
    2)What is its efficiency is it possible to run a 12V battery through this inverter for more than 120 minutes (in case the match goes into extra time)

    If there is a simpler, cheaper alternative circuit can you give suggestions please.

    NB: Do not suggest that I buy one from shops
