Jung, Jee-Hoon, Auteur ; Kwon, Bong-Hwan, Auteur |A corrosion model of a rotor-bar-under-fault progress in induction motors is presented for simulations of induction machines with a rotor-bar fault. A rotor-bar model is derived from the electromagnetic theory. A leakage inductance of the corros[...]

Kwon, Jung-Min, Auteur ; Kwon, Bong-Hwan, Auteur ; Nam, Kwang-Hee, Auteur |In this paper, a grid-connected photovoltaic (PV) multistring power conditioning system with PV input current reduction control is proposed. An improved maximum power point tracking (MPPT) method for the multistring converter is suggested. The s[...]

Kwon, Jung-Min, Auteur ; Nam, Kwang-Hee, Auteur ; Kwon, Bong-Hwan |A photovoltaic (PV) power conditioning system (PCS) with line connection is proposed. Using the power slope versus voltage of the PV array, the maximum power point tracking (MPPT) controller that produces a smooth transition to the maximum power[...]
