Terminal voltage regulation characteristics by static var compensator for a three-phase self-excited induction generator
TL;DR: In this paper, a three-phase self-excited induction generator (SEIG) with squirrel-cage rotor is presented along with its operating performance evaluations for small-scale clean renewable and alternative energy utilizations.
Journal ArticleDOI
A High Frequency-Link Secondary-Side Phase-Shifted Full-Range Soft-Switching PWM DC–DC Converter With ZCS Active Rectifier for EV Battery Chargers
TL;DR: In this paper, a new prototype of a secondary-side phase shift soft-switching PWM dc-dc converter suitable for electric vehicle battery charging systems is presented, and its operating principle is presented on the basis of theoretical analysis and simulation results.
Journal ArticleDOI
Load-adaptive frequency tracking control implementation of two-phase resonant inverter for ultrasonic motor
TL;DR: In this article, a two-phase high-frequency inverter using parasitic resonant impedances incorporated in the ultrasonic motor, which is represented in terms of an electrical resonant tank circuit model, is proposed as a high-power density switching mode ultrasonic power amplifier.
Journal ArticleDOI
Advanced control of PWM converter with variable-speed induction generator
TL;DR: Different control principles, indirect vector control and deadbeat current control, are developed for a voltage source pulsewidth-modulation (PWM) converter and the three-phase variable-speed squirrel-cage IG to regulate dc link and generator voltages with the newly designed phase-locked loop circuit.
Journal ArticleDOI
Series resonant ZCS-PFM DC-DC converter with multistage rectified voltage multiplier and dual-mode PFM control scheme for medical-use high-voltage X-ray power generator
TL;DR: In this paper, a series resonant high frequency transformer-linked multistage DC voltage multiplier was proposed for X-ray power generator applications, where the secondary turn numbers and secondary-side stray capacitance of the high-voltage, high-frequency transformer, as well as the rectifier diode voltage ratings were reduced.
