Hybrid Modulation Strategy for the Vienna Rectifier

Virtual Flux Based Direct Power Control on Vienna Rectifier

This paper proposes the virtual flux based direct power control for Vienna rectifier. No need for the input voltage sensors, the current regulation loop and PWM voltage modulation block along with the active and reactive power decoupling are some of the salient advantages of this method that make it suitable for controlling the conventional active rectifiers. However, due to the three-level nat...

Control Strategy for Three Phase PWM Rectifier Using SVM Modulation

This paper deals with the control of three phase PWM rectifier model using SVM based current controller. In many power electronics control applications the rectifier plays vital role during AC/DC power conversion. The SVM-based HCC scheme is simulated using MATLAB simulink. The technique combines the best features of the SVM and HCC techniques. The controller determines a set of state space vec...

An Improved Modulation Strategy for a Hybrid Multilevel Inverter

Multilevel cascaded and hybrid inverter systems conventionally use three level bipolar PWM for each individual inverter, with their carriers phase shifted to achieve maximum harmonic cancellation within each phase leg. This has been shown to give a harmonic performance equivalent to APOD modulation of a NPC multilevel inverter, when the switching frequencies are scaled to achieve the same numbe...

A Genetic-Fuzzy Control Strategy for Parallel Hybrid Electric Vehicle

Hybrid Electric Vehicles (HEVs) are driven by two energy convertors, i.e., an Internal Combustion (IC) engine and an electric machine. To make powertrain of HEV as efficient as possible, proper management of the energy elements is essential. This task is completed by HEV controller, which splits power between the IC engine and Electric Motor (EM). In this paper, a Genetic-Fuzzy control strategy...
