In this letter, a printed wide-slot antenna array for UWB applications is proposed. By connecting small rectangular structure at the bottom of the elliptical slot and rotating the elliptical patches, the impedance matching can be enhancement. The impedance bandwidth is reached 131% from 2.9 GHz to 14 GHz. In addition, the E-plane and H-plane of the array are bi-directional radiation patterns which...
This paper presents an energy efficient full-duplex (FD) current-mode transceiver for on-chip global interconnects. As it shares the same signaling port for transmitting and receiving signal, the wire efficiency is increased by $2\times $ compared to unidirectional transceivers. The proposed hybrid transceiver has a directional inverter/buffer (DIB) circuit which inverts the outbound signal whereas...
This paper proposes the simple and seamless operation technique for bi-directional LLC resonant converter. Generally, bi-directional operation of LLC resonant converter is complicated and difficult to control. Because, the switching frequency has to be changed across fsr (series resonant frequency) and the switching sequences (the switching timing between high voltage side and low voltage side) has...
In renewable energy systems such as the PV system, the batteries are connected to ensure a stable supply of energy. Therefore, the bi-directional power conditioners have a key role in renewable power systems. In this paper, bi-directional LLC resonant converter as the power conditioner is proposed. The ac analysis and operating characteristics of bi-directional LLC resonant converter are investigated.
So far, the operating characteristics of asymmetry type current resonant converter as LLC converter are discussed in detail. However, the detail operating characteristics discussions of symmetry type resonant converter have not been carried out. This paper investigates the AC characteristics of symmetry type bi-directional current resonant converter, and their soft-switching regions are also investigated.
