In this paper, two reversible single-phase to three-phase ac drive systems are proposed. They are composed of a single induction motor fed by two parallel single- phase to three-phase dc-link converters without isolation transformers. For sake of generalization a configuration composed of three parallel single-phase to three-phase dc-link converters is also(More)
—A new design of an efficient batteryless pumping system powered from photovoltaic panels, comprising a push–pull converter and an induction motor, is presented. Detailed evaluation of the energy processing cycle has allowed the formulation of a set of design principles and the optimization of a sensorless induction motor drive system. The resulting(More)
