The inductor-based and capacitor-free bipolar pulse converter can be applied to electric vehicle charging realize an efficient reliable charging-control strategy. Inductor-based converters avoid the failure caused by of energy storage capacitors improve reliability. An overvoltage protection scheme based on active clamping topology is used protect this when load impedance too large. This take e...

This paper describes the Q enhancement of inductor or resonance circuit based on the controlled CMOS transonductance, which is applicable to either on-chip inductor or off-chip inductor. The proposed circuit configuration of high Q enhancement is evaluated for the RF transmit filter of a LTE mobile comm’s micro base station, with the Q factor of over 3000 and the capacity of 10W. A tunable filt...

This paper presents a novel direct power control (DPC) strategy based on an optimized sector division for three-phase coupled inductor-based bipolar output active rectifier (TCIBAR) applied in more electric aircraft (MEA). First, the instantaneous theory, model of TCIBAR is built synchronous rotating coordinate system. Second, to implement hysteresis without causing runaway zero-sequence curren...

Abstract— This paper develops a method of modelling and designing air-gapped ferrite inductor as filter for large current application of grid-tied inverter. The design method incorporates magnetization curve of the ferrite materials while the modelling of the inductor is based on inverse JilesAtherton model. The dynamic performance of the designed ferrite inductor in the DC-AC inverter circuit ...

The structure of the miniature three–dimensional (3-D) inductor is presented in this paper. The proposed miniature 3-D inductors have been fabricated in a standard digital 0.35m one-poly-four-metal (1P4M) CMOS process. According to the measurement results, the self-resonance frequency SR of the proposed miniature 3-D inductor is 34% higher than the conventional stacked inductor. Moreover, the p...

This work focuses on the possibility of using a tuned inductor in electric power systems with adaptive features. The presented idea operation, an interaction magnetic fluxes, is new approach to designing such devices. Examples are devices for improving quality electricity. Therefore, various types ‘compensators’ reactive (or both and distortion power) used electrical as preventive measure. indu...

A high Q-factor (quality-factor) spiral inductor fabricated by the CMOS (complementary metal oxide semiconductor) process and a post-process was investigated. The spiral inductor is manufactured on a silicon substrate. A post-process is used to remove the underlying silicon substrate in order to reduce the substrate loss and to enhance the Q-factor of the inductor. The post-process adopts RIE (...

Environmentally relevant contaminants endowed with chirality may include pharmaceutical compounds, flame retardants, perfluoroalkyl chemicals, pesticides, and polychlorinated biphenyls. Despite having similar physicochemical properties, enantiomers differ in their biochemical interactions enzymes, receptors, other chiral molecules leading to different biological responses. In this work, we have...

A striped inductor and its utilization of a voltagecontrolled oscillator (VCO) are studied with the aim of suppressing phase noise degradation in Kand Ka-bands. The proposed striped inductor exhibits reduced series resistance in the high frequency region by increasing the cross-sectional peripheral length, as with the Litz wire, and the VCO of the striped inductor simultaneously exhibits a lowe...
