Modeling and Control For a Type-4 Wind Generator Based on AC/AC Power Converter

IEEE International Autumn Meeting on Power, Electronics and Computing, 2019
In this work a control scheme for a Type-4 wind turbine of 30 kW, is presented. The scheme is based on the control of currents obtained from the dq0 framework. The AC/AC power converter is designed based on the generator characteristics.

A Five-Switch Single-Phase Buck–Boost AC–AC Converter With Inherent Commutation and Continuous Input Current

IEEE transactions on power electronics
In this article, a five-switch single-phase buck–boost ac–ac converter with inherent commutation and continuous input current is proposed. The proposed converter only requires five switches, which sets it apart from other nonisolated ac–ac buck–boost ...

Comparative Evaluation of Control Dynamics of 3-Φ AC–AC Current DC-Link and Voltage DC-Link Converters Based on DC–DC Equivalent Models

IEEE Journal of Emerging and Selected Topics in Power Electronics
Variable speed drives (VSDs) operating from the mains can be realized either with a voltage dc-link/voltage-source converter (VSC) or, alternatively, with a current dc-link/current-source converter (CSC), which has received renewed interest recently due ...

Experimental Comparison of Three-Phase AC–AC Monolithic Bidirectional GaN Transistor-Based Current DC-Link Converter and GaN Transistor-Based Voltage DC-Link Converter

IEEE Journal of Emerging and Selected Topics in Power Electronics
Grid-connected variable speed drives (VSDs) are ac–ac converters that ideally provide smooth sinusoidal output voltages for compatibility with standard motors, avoiding overvoltage and/or EMI issues if long motor cables are used.
