I've been building a 300W inverter. This one is from Electronics Australia, June 1982, and was based on the Feb 1979 EA design. I've added an auto start circuit and improved the overload protection circuit. An unfortunate aspect of both the 1979 and 1982 designs was the voltage regulation circuit prevents the inverter powering low power factor loads. They are thus unsuitable for running anything with an induction motor, or fluorescent lamps with no power factor correction.
