Abstract
DC-DC converters (DDC)to settle down switching noise into regulatedDirect Current (DC) voltages utilize High-Frequency (HF) switching, inductors, transformers, together with capacitors. They are HF powerconversioncircuits and are common in portable, battery-operated, and other higher-efficiencysystems. Whilst boosting, lessening, or inverting supply voltages, these converters can render efficiencies more than 95%. There was a considerable enhancement in the system’s Power Density (PD), efficiency, together with dynamic characteristics with the advancement of HF-DDC. In DC grid, transportation, aerospace, renewable energy, point-of-load (POL) power supply, as well as numerous other fields, HF-DDCs were implemented. The major concerns under high Switching Frequency (SF) are switching loss in tandem with magnetic loss. To acquire an inclusive enhancement in its efficiency along with PD, it is indispensable to widely deem the influence betwixt the device, topology, in addition to other aspects in the designing process of HF-DDCs. Disparate techniques that were employed to ameliorate the DDCs’ efficiency with optimized Switching Control (SC) are surveyed here. The opportunities along with challenges in future development are summed up with their equivalent topics, and it mainly concentrated on the efficient DDC with optimized SC. This review can well be of useful guidance in designing effectual DDCs.
