Comparison Between PI Controller and Fuzzy Logic-Based Control Strategies for Harmonic Reduction in Grid-Integrated Wind Energy Conversion System

In this paper, a six-switch AC/DC/AC converter is proposed for single-phase wind energy system application. The proposed converter consists of two arms with three switches in each, where the top layer switches are used for the rectification mode and lower layer switches are used for the inversion mode of operation. The middle layer switches are shared by the both rectification and inversion mode operation based on the modified PWM scheme. A small rated DC link capacitor is chosen by providing suitable coordination control and EX-OR gate logic between the rectification and inversion mode of operation. The proposed single-phase six-switch converter has the advantage of both reduced number of switches and small DC link capacitor size. To validate the effectiveness of the proposed converter, simulation results are presented for 1, kW wind system. © Springer Nature Singapore Pte Ltd. 2018.

A Novel Six-Switch Power Converter for Single-Phase Wind Energy System Applications

In this paper, an isolated high step-up single switch DC-DC converter for renewable energy source is proposed. In the proposed converter high step-up voltage is obtained by single power switching technique that operates low duty cycle with isolated transformer inductors and switched capacitors and power diodes. The disadvantage of conventional converters is that it has high duty ratio and high voltage stress on power devices with less efficiency. The proposed converter eliminates the switching losses and recycles the leakage energy which includes reverse recovery energy of the power diode by using passive clamp circuit. To achieve high output voltage gain, the isolated transformer primary terminal and secondary terminal are connected in series during switching operation. PSIM software has been used for simulation. Simulation circuit is analyzed at 40Vdc/400Vdc, 200 W and this operation is validated by implementing in the hardware model at 12Vdc/120Vdc, 60 W. Â© 2014 Production and hosting by Elsevier B.V.
