The purpose of this paper is to present an efficient converter circuit used to drive switched reluctance motors. It uses the C-dump topology in which the trapped energy in the phase windings is returned to the supply capacitor to be used in the following strokes. In addition to the C-dump topology, it uses two extra feedbacks. One comes from a governor mounted on the shaft of motor which contro...

This paper introduces a new bidirectional, isolated dc–dc converter. A typical application for this converter can be found in the auxiliary power supply of hybrid electric vehicles. A dual half-bridge topology has been developed to implement the required power rating using the minimum number of devices. Unified zero-voltage switching was achieved in either direction of power flow with neither a...

Power quality (PQ) problems for renewable energy system (RES) is major challenge using these systems. Amplitude, frequency, and waveform important PQ parameters especially standalone or isolated In this paper we propose RES with wind turbine (WT) permanent magnet synchronous generator (PMSG) to feed different loads (liner, non-liner) through AC-DC-AC converter. The PMSG operate fuzzy logic iner...

Hybrid electric vehicles (HEVs) offer many advantages, such as high fuel economy, low emissions, and silent operation. In HEVs, there are two or more different voltage buses for different purposes of the vehicle operation. There are needs of galvanically isolated bidirectional DC-DC converter to link different DC voltage bus and transfer energy back and forth. For example, on of the DC-DC conve...

This paper presents the design and implementation of a power converter for an autonomous wind induction generator (IG) feeding an isolated load through the PWM-based novel soft-switching interleaved boost converter. The output voltage and frequency of the wind IG is inherently variable due to random fluctuation of wind-speed variation. The interleaved boost converter composed of two shunted ele...

This paper presents a new method for theoretical stability analysis of a bidirectional dual full bridge DC-DC converter with triple phase-shift control. The developed approach is analytically sound and generally applicable when compared with the existing approaches, which are by and large based on computer simulation. The operating process of a bidirectional converter is multi-stage and nonline...

Abstract The Isolated AC/DC matrix converter realizes bi-directional energy transmission through phase shift control. existing control schemes do not coordinate the modulation coefficient and ratio well, which will cause large current stress to converter, resulting in low efficiency. To solve this problem, paper analyses working mechanism of IAMC under dual It constructs a mathematical model ca...
