Rele a TPS7A78, li se yon trè avanse pran sou teknik la dekad-fin vye granmoun kapasitif gout, ki sèvi ak enpedans la seri nan yon CAPACITOR ('CS' nan ka sa a) nan frekans ak elektrisite 'lach' anpil nan ak elektrisite vòltaj la san pèt pouvwa reyèl (nan pri a nan yon faktè pouvwa malere).

Called the TPS7A78, it is a very advanced take on the decades-old capacitive dropper technique, which uses the series impedance of a capacitor (‘Cs’ in this case) at mains frequency to ‘loose’ much of the mains voltage without real power loss (at the price of an unfortunate power factor).
