An Advanced Current Control Strategy for Three-Phase Shunt Active Power Filters
Quoc-Nam Trinh,Hong-Hee Lee +1 more
TL;DR: The proposed control scheme requires only two current sensors at the supply side and does not need a harmonic detector, and the performance of the APF is improved significantly compared to the traditional control scheme, thanks to the effectiveness of the proposed compensation scheme.
Journal ArticleDOI
Algorithms for Controlling Both the DC Boost and AC Output Voltage of Z-Source Inverter
TL;DR: The algorithm to control linearly the capacitor voltage is suggested in order to improve the transient response for DC boost control of the Z-source inverter.
Journal ArticleDOI
PLL-Based Seamless Transfer Control Between Grid-Connected and Islanding Modes in Grid-Connected Inverters
TL;DR: In this article, a phase-locked loop (PLL)-based seamless transfer control method between grid-connected and islanding modes in a three-phase gridconnected inverter is proposed.
Journal ArticleDOI
Sensorless Control of BLDC Motor Drive for an Automotive Fuel Pump Using a Hysteresis Comparator
TL;DR: This paper develops the brushless dc (BLDC) motor sensorless control system for an automotive fuel pump that is based on a hysteresis comparator and a potential start-up method with a high starting torque.
Journal ArticleDOI
Input Power Factor Compensation Algorithms Using a New Direct-SVM Method for Matrix Converter
TL;DR: A new direct space vector modulation (DSVM) method to achieve the required displacement angle between the input voltage and input current of the MC system is proposed and a new switching strategy is introduced based on the maximum compensated angle.
