Power supply - Circuitos electrónicos

Power supply
This supply uses no heavy step down transformer and has an extremely low parts count. The circuit can be built very small and can supply small currents for small projects. The major downfall of this supply is that it is not isolated from the AC line and can only supply small currents.

This circuits was used to provide battery backup to a device that had an AC (output) wall transformer. Due to the quaise-sine-wave output and imprecise 60Hz output frequency, some devices might not work properly. Peak output is the DC input voltage minus about 20 ohms drop. Use bigger output MOSFETs for more current outputDiscovercircuits.com is your portal to free electronic circuits links. Copying content to your website is strickly prohibited!!!.......
