High Gain Efficient Interleaved Dc-Dc Converter for Induction Motor Applications
Abstract
Large electric drives and utility applications require advanced power electronics converter to meet the high power demands. In order to meet the required load demand, it is better to integrate the renewable energy sources with the application of drive connected scheme by using inverter module. A novel interleaved high step-up converter with voltage multiplier cell is proposed in this paper to avoid the extremely narrow turn-off period and to reduce the current ripple. The voltage multiplier cell is composed of the secondary windings of the coupled inductors, a series capacitor, and two diodes. Furthermore, the switch voltage stress is reduced due to the transformer function of the coupled inductors, which makes low-voltage-rated MOSFETs available to reduce the conduction losses. Additional active device is not required in the proposed converter fed induction motor drive using inverter module, which makes the presented circuit easy to design and control. The simulations results are conferred using Matlab/Simulink platform.
