Background: A comparative analysis of Sliding Mode Control (SMC) and conventional average current control (AvCC) of a single phase low harmonic rectifier (LHR) having a DC--DC converter is presented. Methods: The SMC which hitherto has been extensively deployed in the control of DC-DC converters is combined with an aspect of AvCC to effectively harness their individual benefits in the control of a LHR. Amongst the four c Read More

Background: In this paper, we propose a redundancy configuration method for Modular Multi-level Converters (MMCs), to improve system reliability and sub-module efficiency, and for maximizing the redundant sub-module value rate. Methods: We establish a set of objective functions using these aims, to obtain the optimal number of redundant sub-modules. To aid in the evaluation of the configuration method, we analyzed the M Read More

Background: Currently, power control of PV generation focuses on the Maximum Power Point Tracking (MPPT) strategy, with which PV systems is sensitive to the light, temperature, and micro-grid state, and introduces power fluctuation to the micro-grid. Methods: With the schedulable requirements of Photovoltaic (PV) systems in the grid-tied mode, PV generation systems should possess constant power output capabilit Read More
