A Novel High Voltage Gain with Boost–Fly Back Converter for PV Fed Induction Motor Drive
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 11
Abstract
In rural areas renewable energy sources plays a key role in power generation and transmission. Where the power transmission from conventional energy sources is complicated, bulky electric drives and utility applications required, power converter construction has been introduced as a substitute in medium voltage and high power requirements using Renewable Energy Systems. Additional merits of renewable power source are light, dirt free and pollution free operation. By using inverter module in order to meet the required load demand, it is better to integrate the renewable energy power with the application of drive connected system by using inverter module. An advanced power electronics converter is used to meet the high power load applications. A new interleaved high step-up boost-fly back converter with voltage multiplier cell is proposed in this paper to avoid the extremely narrow turn-off period and to decrease the current ripple. The voltage multiplier module is composed of the secondary windings of the coupled inductors, a series capacitor, and two diodes. In addition, the switch voltage stress is reduced due to the transformer function of the coupled inductors, which makes low-voltage-rated MOSFETs offered to reduce the conduction losses and increases the lifetime of the input source. Which makes the presented circuit uncomplicated to design and control, additional active device is not required for the proposed converter fed induction motor drive using inverter module. The simulations results are conferred using Mat lab/Simulink.
