In this letter, the compressive sensing (CS) is utilized to accelerate the matrix filling procedure of the traditional method of moments (MoM). Instead of constituting a fully populated matrix as the traditional MoM typically does, the CS technology allows one to establish an underdetermined linear system, and the unknown induced currents can be reconstructed by finding the smallest possible $\ell _1 $...
This paper presents a novel iterative non-breakdown rectifier topology which would practically solve the rectifier's early breakdown problem in multi-sine wireless power transmission (WPT) for biomedical application. The proposed rectifier holds an iterative topology which can extend the reverse breakdown voltage limitlessly with its forward threshold voltage remains. It keeps high conversion efficiency...
Intrabody communication (IBC) is a promising technology that enables the improvement of digital healthcare devices. IBC uses the human body as a transmission media, and the accurate transmission model is important for the design of transceivers. In the measurements of transmission characteristics, baluns have been widely used to separate the grounds of transmitter and receiver. In this work, we analyze...
Recently, wide bandgap semiconductors are extremely attractive for the gamut of power electronics applications from power conditioning to RF/microwave transmitters for communications and radar systems. Of the various wide bandgap materials and device technologies, the AlGaN/GaN high-electron mobility transistor seems the most promising. This paper attempts to investigate the status of updated GaN...
This paper presented a novel resonant electric field sensor (EFS) based on SOI fabrication process for power engineering applications. The sensor architecture has three major blocks: a vibration shutter, sensing electrodes, and a driving electrode that feeds back to the shutter. The EFS structure is designed to work at resonant frequency for maximum sensitivity to electric fields. Prototyped by the...
Metal oxide arresters (MOAs) are widely used on HV transmission lines for over-voltage protection. However, it is still difficult to carry out its on-line monitoring, because of some bottlenecks such as the installation of sensor, signal transmission and on-site power supply, et al. This paper first discusses the improved acquisition sensor for getting leakage current value and recording the number...
