ABSTRACT This paper presents a speed controller using a fuzzy-logic controller (FLC) for indirect field oriented control (IFOC) of induction motor (IM) drives fed by a four-switch three-phase (FSTP) inverter. In the proposed approach, the IM drive system is fed by...
ABSTRACT This paper proposed an improved topology for a high efficiency PWM DC-AC grid-connected PV inverter that utilizes a zero-voltage-transition (ZVT) auxiliary network to provide soft-switching condition. In this paper, a soft-switching method using ZVT technique...
ABSTRACT This paper compares Space Vector Modulation (SVM) strategies for multiphase inverters. Symmetric, discontinuous, and group-based SVM and Sinusoidal Pulse Width Modulation (SPWM) are compared against each other. Implementation techniques for n-phase modulation...
ABSTRACT This paper proposes a bidirectional three-level LLC resonant converter with a new pulse width and amplitude modulation (PWAM) control method. With different control signals, it has three different operation modes with different voltage gains. Therefore, it...
ABSTRACT This paper presents a highly efficient asymmetrical pulse-width modulated (APWM) full-bridge converter for renewable energy sources. The proposed converter adopts full-bridge topology and asymmetric control scheme to achieve the zero-voltage switching (ZVS)...
ABSTRACT A bidirectional converter (BDC) is essential in applications where energy storage devices are involved. Such applications include transportation, battery less UPS, Flywheel Energy Storage (FES) systems etc. Bidirectional power flow through buck and boost mode...
