This paper presents a simple approach for implementation of a Space Vector Pulse Width Modulation (SVPWM) Technique for control of three phase Matrix Converter (MC) using MATLAB/Simulink & FPGA Software. The Matrix converter is a direct AC/AC Power conversion without an intermediate DC link. This converter is inherently capable of bi-directional power flow and also offers virtually sinusoidal i...

In this paper we prove the existence and uniqueness of the solution of a non-stationary problem that modelizes the behaviour of the concentrations and the temperature of gases going through a cylindrical passage of an automotive catalytic converter. This problem couples parabolic partial differential equations in a domain with one parabolic partial differential equation and some ordinary differ...

A single-phase ac-to-dc converter using threephase modified series-parallel resonant converter is proposed in this paper. The three-phase resonant converter is analyzed using Fourier series approach. The design curves for a resonant converter of 2.5 kW rating are plotted. The converter components are selected based on the design curves. The converter is simulated for different load conditions u...

It is well known that hydrogen addition to spark-ignited (SI) engines can reduce exhaust emissions and increase efficiency. Micro plasmatron fuel converters can be used for onboard generation of hydrogen-rich gas by partial oxidation of a wide range of fuels. These plasma boosted microreformers are compact, rugged, and provide rapid response. With hydrogen supplement to the main fuel, SI engine...

Received Oct 9, 2017 Revised Nov 14, 2017 Accepted Nov 26 , 2017 This paper presents the design and analysis of a novel polygon connected autotransformer based 30-phase ac-dc converter which supplies direct torque controlled induction motor drives (DTCIMD’s) in order to have better power quality conditions at the point of common coupling.

Harmonic pollution and low power factor in power systems caused by power converters have been of great concern. To overcome these problems several converter topologies using advanced semiconductor devices and control schemes have been proposed. This investigation is to identify a low cost, small size, efficient and reliable ac to dc converter to meet the input performance index of UPS. The perf...
