The traditional Phase-Shift Full-Bridge Converter (PSFBC) cannot achieve Zero-Voltage Switching (ZVS) at light loads due to small resonant current resulting in low conversion efficiency at light loads. Therefore, a light-load conversion efficiency improvement strategy for PSFBC is emerging and needs to be realized. A novel dead-time adjustment strategy for light-load conversion efficiency improvement...
Advanced Metering Infrastructure (AMI) plays an important role in smart grids. Data Concentrator Unit (DCU), used to collect data from smart meters and transmit them to Meter Database Management System (MDMS) regularly, is the core component in AMI. If DCU can provide value-added functionalities, more efficient AMI management can be achieved. Therefore, this paper designs and develops IEC61850 as...
A novel 4-times voltage multiplier rectifier with smart Time-Division-Multiplexing (TDM) control strategy for high step-up converters is proposed in this paper. Based on the proposed TDM control strategy, two full-wave voltage doubler rectifiers can be combined to realize the proposed 4-times voltage multiplier rectifier. The novel 4-times voltage multiplier rectifier and TDM control strategy can...
