This paper proposes a novel methodology based on the recent metaheuristic grasshopper optimization algorithm (GOA) for extracting the maximum power from a wind energy system operated under variable speed conditions. The proposed system comprises a permanent magnet synchronous generator operated via a wind turbine, a dc-dc boost converter, a three-phase diode rectifier, and a maximum power point tracker (MPPT) designed via the proposed GOA. The proposed MPPT tunes the duty cycle of the boost conv...

This paper introduces a 3-level of phase-shift ZVS-PWM with H bridge DC/DC with high power converter at a high-frequency link for arc welding machine. The proposed model has reduced filter size, improved dynamic response and reduced voltage losses on the semiconductor switches. Current doubler circuit is inserted on the secondary side of in a converter, and a high-output current is produced from the secondary-side circuit so, efficiency may be getting better by using current doubler rectifier (C...

Modular Multi-level Converters (MMCs) are considered as one of the promising multilevel converter topologies specially in high voltage applications such as HVDC transmission systems. The idea behmd MMC is to use floating capacitors as a voltage sources along with a switchmg circuit (chopper cell) to form what is called “submodules”. These submodules are inserted or bypassed according to the required output voltage level. To ensure a stable operation, submodule capacitor voltages should be kept m...

In this paper, a control strategy optimized by Mine Blast Algorithm (MBA) is applied on a variable speed wind generator (VSWG) system based on a doubly fed induction machine. The proposed MBA is applied to evaluate the optimal parameters of the current PI controller such that obtaining rotor current closes to the desired one; this purpose is achieved by minimizing the sum of squared error (SSE) between two currents. A direct closed loop control of stator current is taken place to regulate the re...
