On the Highly Stable Performance of Loss-Free Optical Burst Switching Networks

open access: yesAdvances in Electrical and Electronic Engineering, 2016
Increase of bandwidth demand in data networks, driven by the continuous growth of the Internet and the increase of bandwidth greedy applications, raise the issue of how to support all the bandwidth requirements in the near future. Three optical switching

Depth comparison of common inductor and common capacitor passive current sharing methods for multiphase LLC converter

open access: yesIET Power Electronics, 2023
Common inductor (CIM) and common capacitor (CCM) passive current‐sharing methods have the advantages of simple implementation and low cost. However, there is still a lack of detailed comparative research on the two methods, which makes researchers ...

Soft switch-avalanche IGBT convertor

open access: yesElectronics Letters, 1990
A full bridge dc-dc converter using a zero voltage and zero current switching technique is described. This circuit utilizes the characteristics of the IGBT to achieve power and frequency combinations that are much higher than those previously reported for this device.

IGBT convertor with active snubber for soft switching

open access: yesElectronics Letters, 1991
This full bridge dc-dc convertor with IGBTs uses zero voltage switching (ZVS) for one leg of the bridge and zero current switching (ZCS) for the other. It is shown that an active snubber greatly improves the performance over previous methods. Experimental results are shown for a 6 kW circuit switching at 20 kHz.

New bilinear switched-capacitor immittance convertor circuit

open access: yesElectronics Letters, 1980
A new switched-capacitor immittance convertor circuit is proposed which enables the conversion of the capacitive (n+1)-terminal networks into the corresponding bilinearly equivalent inductive (n+1)-terminal networks. The proposed immittance converter circuit requires only two operational amplifiers and five capacitors.

Characteristic curves for analysing limit cyclebehaviour in switching convertors

open access: yesElectronics Letters, 1999
The concept of characteristic curves (CCs) for analysing the behaviour of limit cycles in elementary DC-DC switching converters is introduced. The CC is derived by considering opposite vector fields in the on and off configurations. Feedback regulated converters with PWM or hysteresis control are investigated using this approach.

Improved switched-capacitor algorithmic analogue-to-digital convertor

open access: yesElectronics Letters, 1985
A novel switched-capacitor circuit is presented for algorithmic analogue-to-digital conversion. Besides the reduced component count, the proposed circuit shows that it can accept a differential analogue signal. A conversion accuracy higher than 12 bits is easily attainable with its integrated version.

Semiconductor loss calculation of DC–DC modular multilevel converter for HVDC interconnections

open access: yesHigh Voltage, 2018
DC–DC modular multilevel converter (DC–DC MMC) is an attractive candidate for high-voltage DC (HVDC) interconnections since it can provide the required voltage matching, galvanic isolation and flexible power control abilities.
