A High Voltage Gain Boost Converter: Concept of DC Power Transfer Using Mutual Inductors

Saurav Bharadwaj, Indrajit Barman, Midar Riba, Asish Arpan Dadhara, Biswajit Sengupta


A high voltage boost converter is being prototyped in an artificial software-based environment of MATLAB/ SIMULINK and identifies the practical conditions of the converter. A direct current (DC) input voltage is being boosted to a higher magnitude by multiplying a gain factor in a dynamic process of DC power transfer by cascading three mutual inductors in a single core. Input voltage is being switched by primary IGBT switches creating simultaneous charging and discharging of primary inductor, hence induces identical voltage in two secondary inductors. Inductors are charged and power is transferred to a parallel capacitor and finally to the resistive load in accurate control of duty cycles.


Coupled inductors, Voltage spikes, Semi-conductor switches, Switching frequency, Voltage boosting, DC power transfer and Voltage ripples.
