Guest Editorial Special Issue on Emerging Converter Topology, Operation, and Design Technologies

Power electronics play a key role in the transition to carbon neutrality. To enhance the performances of power electronics systems, new theories and methods are entering the field of power converter research, leading to increasing diversity of the knowledge database regarding converter design and operation methods. In addition to the conventional case-bycase design methodology, new automated and generalized converter design philosophies integrating topology derivation and synthesis methods, optimal pulse-width modulation (PWM), and advanced control strategies are gaining attention in both academia and industry. By implementing these methods, the converter design process can be greatly improved while the potentials of various power converters can be fully explored, leading to elevated converter performances.
