A venit recent un amic la mine sa ii fac o sursa de alimentare pentru o masina de tatuat.. Aceasta are doua bobine.. nu am apucat inca sa le masor. Ideea e ca el doreste ca sursa sa fie reglabila.. Eu ma gandeam sa adopt o schema de generator PWM pentru a regla turatia/bataia masinariei.. Va intreb si eu pe voi , daca ati facut asa ceva , si daca este ok solutia pe care doresc sa o adopt :nas:

aparatul e cumparat.. are doua bobine dupa cum spuneam , dar inca nu am apucat sa=- masor rezistenta.. maine banuiesc ca va ajujunge acel aparat din nou la mine. si functioneaza cu curent continuu , deoarece circuitul este intrerupt de o lamela metalica gen platina de delcou , cu un condensator in paralel cu circuitul comutat pentru a reduce scanteia.. asa din cate imi amintesc , bobinele au in jur de 8 ohmi dar nu stiu sa zic exact daca sunt legate in serie sau in paralel. Aparatul arata cam asa:
