The next 3 V to 220 V inverter circuit is designed to work in a blocking oscillator mode having an operating frequency set at around 400 Hz. The transistor used can be any PNP power transistor. The center tap transformer can be any standard step down transformer. This transformer provides the feedback and the voltage boosting both together.
This 3 V to 220 V inverter circuit may draws around 70 ma from the 3 V battery (B1). The inverter circuit seen above is built around a straightforward astable multivibrator, which pushes and pulls its output via the secondary of a center-tapped, 12-volt step down power transformer. The circuit is powered by 6 volts of DC from four AAA batteries.
Re: 220v from two inverters? You can put in series (two 120 VAC units into "one" 240 VAC w/ neutral unit), if the units you have have been designed for synchronized operation (I believe, with an external control cable that runs between the two units--such as some Outback units will).
You would have to get a step-up transformer (perhaps auto-wound for lower costs) to get 220 from a 110 inverter. Re: 220v from two inverters? Aloha, Can I parallel two of the same MSW inverters @ 110v each and get 220v single phase? If so, then would I tie the two neutrals together? Reference my system below. thanks
