The result is a fast amplifier (>80V/us slew rate) with low distortion (0.00045% meadured @ 1kHz/1W/8ohm resistive load). It's undergone some preliminary measurements and looks quite promising.


Ogbonna-Joseph/1KVA-SINE-WAVE-POWER-INVERTER
This is a design of a sine wave power inverter, which can be used in your homes and offices.
It measures 116.5 × 47.5 mm and has 2 copper layers, 1.6 mm thick.
27 parts, built around the BC337, 100SP1T1B4M2QE, BD139 and BD140. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the Edson8101/EA801---Turma-D repository on GitHub, at the commit this page was made from: the board is Projeto 03/Projeto3_Barbara_Glauco/Projeto_Boost/proj3_potencia.kicad_pcb and its schematic Projeto 03/Projeto3_Barbara_Glauco/Projeto_Boost/proj3_potencia.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
