This Project introduces a novel type of 3-phase single stage dc-ac converter, which is controlled by sliding mode control, offers intrinsic step up abilities. Proposed inverter is designed with the lesser number of solid-state semiconductor switches and small passive elements. Sliding mode controller (robust controller) is designed to control this power converter in order to achieve high robustness,sustain any kind of line or load variations and achieve a good dynamic response. In addition to this, the voltage across every capacitor is less when compared with existed traditional boost inverter topologies, which leads to better reliability and enhanced life span of the converter. This scheme also offers very less harmonic in the output voltage and currents. Proposed scheme is tested for different line and load varying conditions on MATLAB Simulink environments as well as on a prototype.A 500W prototype has been fabricated and experimented to validate the feasibility and benefits of the system.Simulation and Experimental results reveal that proposed inverter offers better reliability, power quality and high life time over the existed topologies.
A novel energy recirculation circuit, utilizes the concept of energy recirculation, with the power augmentation capability is proposed. Proposed ERSC can be used as device in-situ testing unit,by utilizing naturally occurring high electrical stresses on devices from a low-cost low-power source-supply energy for high power testing of power electronic devices. This topology allows devices to be examined at full-power stresses without connected mwith high power load and also without demanding high power,by storing and recirculating the energy of the energy storage elements,which elevates the capability of source power. This converter can operate in four different modes of operation, namely, soft-start, magnetize, charge and energy recirculation modes with the four active states of operations attained by two active switches of the proposed converter.Another feature of this converter is, based on the devices under test devices performance these two circuits can be designed to operate in synchronous or asynchronous manner, i.e.faster devices or slower devices can be tested.
For an in-situ testing of high current and/or voltage devices, this circuit offers several advantages such as simple circuit design, does not demanding any high voltage step up transformer for realizing high voltages/currents, can be able to operate from low voltage/ power supply, cheapest solution and also provides fast response in comparison with conventional cascaded boost/buck and cascaded buck/boost ERSCs. To validate the concept, simulations are carried for testing of 1.2KV and 100A using 100V and 8A. And also, the same is going to prove with the help of lab made prototype.
Renewable energy resources will be an increasingly important part of power generation in the new millennium. The main objective of this project is to develop a power conditioning system, which can be used to extract the variable DC power from the sun.It is converted into fixed dc by using DC- DC boost converter and then converted into AC power by using 3- level diode clamped inverter,to feed AC load effectively.In this project simulation results of FPGA Controlled Photovoltaic (PV) power conditioning system for AC loads are presented.The power conditioning system consists of a diode clamped three level inverter fed by closed loop voltage controlled DC- DC Boost converter.This closed loop control of DC- DC converter is implemented by a conventional Pulse Width Modulator (PWM) with duty cycle ratio control method. This boost converter is designed to obtain regulated voltage from the variable DC supply.A level shift sinusoidal PWM is used to control the multilevel inverter on FPGA.
In this project, hardware of Diode clamped 3-level inverter is implemented and is controlled by FPGA Controller. This 3-level inverter is mainly developed for medium level power applications. FPGA has been preferred over a traditional microcontroller because an FPGA can work at frequencies of order of 50MHz, while the latter can work with frequencies up to 5-6 MHz only, making the FPGA faster and more accurate in generation of firing pulses.
The backbone of modern industry is electrical drives.Tremendous changes in speed control of electrical machines have been taken place with the development of power electronics. Now days, AC motors are also used for variable speed applications. At present in speed control of AC machines, single phase Cycloconverters are widely used for AC#AC power conversion. In this project, Single Phase Matrix Converter (SPMC) Topology using IGBT#s as power switches is used for Cycloconverters operation in place of conventional thyristor as it offers number of advantages. In this project, well known Sinusoidal Pulse Width Modulation (SPWM) scheme is used for generating gate pulses to IGBT#s.This project presents work on modelling and simulation of Cycloconverters using MATLAB/Simulink incorporating the Sim Power System Block set.
