High voltage gain boost converter based on voltage lifts techniquesHere are the photography of prototype. The conversion ratio of boost voltage with voltage lifts capability can boost up to 4 times higher than the traditional boost converter. It is simply added two more L and C resonant circuit plus additional diodes to control the current flows for achieving this circuit operation.5868 0 Jul 15.2018, 08:46:30 -
