“…Currently, the research work aiming at inverter is mainly carried out on the modular design of inverters, IGBT thermal balance analysis, performance evaluation, control strategy of cooler, and inverter fault diagnosis [3][4][5][6][7][8][9]. A newly developed dual bi-directional IGBT-based inverter in conjunction with autonomous microgrid system is investigated with particular focus on the thermal management and performance evaluation under various operation conditions in [10], so the inverter is usually equipped with the ventilation and cooling system.…”
