Nano power DC-DC converter in TSMC 22ULL with ultra-low quiescent current and high efficiency at light load, supporting 1.62 V to 3.63 V input voltage. ...
Fuel-cell (FC) vehicles are attracting much interest due to their advantages. In FC-powered vehicles, the application of DC/DC converters is for interfacing between the FC and the DC bus. Due to some of the inherent characteristics of FCs, such as large variations in the output voltage, efficiency improvement for different operation points is vital for optimal performance. Moreover, the bidirectional operation can be useful, for example, to charge supercapacitors in electric vehicles (EVs). In this article, the role of a DC/DC converter is as part of the interface system, and efficiency analys...
A single DCDC converter that can generate all the power supplies from a Li+ battery for a typical SoC or mixed signal IC. Typical output voltages include ...
The DC-DC converter market is dominated by players such as TDK Lambda Corporation (Japan), Texas Instruments Incorporated (US), Delta Electronics (Taipei).
This paper introduces eight novel interleaved non-isolated dc-dc converters with ultra-high step-up and zero voltage switching (ZVS) capabilities for renewable energy systems. To increase the voltage gain, the proposed converters benefit coupled inductors, high-frequency (HF) transformer, and voltage multiplier (VM) techniques. In comparison to other converters, which just benefit coupled inductors or HF transformers, these combinations of the techniques make an additional degree of freedom to achieve high voltage gains (more than 25 without extreme duty cycle). Besides, two active clamp circu...
