Novel High Step-Up Boost Converter with Charge Pump Capacitor

Inhalt:
In order to meet the demands of the distributed generation system converting low dc input voltage from solar, fuel cell and battery to high output voltage, a novel boost converter topology, which contains a charge pump capacitor and double inductors on the basis of the traditional boost converter is proposed in this paper. The proposed converter realize the high voltage gain under low duty cycle by charging through the inductors and capacitor in parallel and discharging through the inductors and capacitor in series. The operation principle and steady state analysis are provided in three different inductance conditions. Finally, the results of the analysis are verified by simulation.
