A quadratic boost converter topology based on a high conversion ratio dc/dc converter with an active zero-voltage switching (ZVS) snubber circuit is developed for PV system application. Combined with a reboost inductor, a coupled inductor and charge-pump circuits are proposed to achieve high voltage gain with quadratic function. A front inductor is proposed to reboost the voltage gain to make the...
A high conversion ratio DC/DC converter with an active zero-voltage switching (ZVS) snubber circuit incorporated with maximum power point tracking (MPPT) techniques is presented in the paper. The MPPT controllers employ photovoltaic (PV) systems to make the converter output track the maximum PV output power. The active snubber circuit restricts the voltage stresses on the power switches. The simulation...
