Implementation and Comparison between Two Algorithms of Three-Level Neutral Point Clamped Voltage Source Inverter
Abstract:
This paper presents a comparison between two Pulse Width Modulation (PWM) algorithms applied to a three-level Neutral Point Clamped (NPC) Voltage Source Inverter (VSI). The first algorithm applied is the triangular-sinusoidal strategy; the second is the Space Vector Pulse Width Modulation (SVPWM) strategy. In the first part, we present a topology of three-level NCP VSI. After that, we develop the two PWM strategies to control this converter. At the end the experimental results are presented.
Keywords:
Multilevel inverter, Space vector pulse width modulation (SVPWM), triangular-sinusoidal strategy.

Experimental Study of Boost Converter Based PV Energy System
Abstract:

This paper proposes an implementation of boost converter for a resistive load using photovoltaic energy as a source. The model of photovoltaic cell and operating principle of boost converter are presented. A PIC microcontroller is used in the close loop control to generate pulses for controlling the converter circuit. To performance evaluation of boost converter, a variation of output voltage of PV panel is done by shading one and two cells.

Keywords:
Boost converter, Microcontroller, Photovoltaic power generation, Shading cells.

Three-Level Converters Back-to-Back DC Bus Control for Torque Ripple Reduction of Induction Motor
Abstract:

This paper proposes a regulation method of back-to-back connected three-level converters in order to reduce the torque ripple in induction motor. First part is dedicated to the presentation of the feedback control of three-level PWM rectifier. In the second part, three-level NPC voltage source inverter balancing DC bus algorithm is presented. A theoretical analysis with a complete simulation of the system is presented to prove the excellent performance of the proposed technique.

Keywords:
Back-to-back connection, Feedback control, Neutral-point balance, Three-level converter, Torque ripple.
