This paper proposes a hierarchical battery balancing architecture for the series connected lithium-ion batteries. The battery cells are grouped into different packs and the bottom layer is the Adjacent Cell-to-Cell structure consisting of the packs. The top layer is connected to different packs and can deliver the energy from one pack to any other pack bi-directionally, leading to high flexibility...
This paper proposes a new current-ripple-based control strategy for the Series Ripple Cancellation Converter (Series RCC), which eliminates LED light flicker caused by Power Factor Correction (PFC) stage and significantly reduces its output capacitance. Instead of sensing two differential output voltage signals as in existing voltage-ripple-based control strategy, the proposed current-ripple-based...
Many inverter topologies have been proposed to eliminate the leakage current of transformerless Full Bridge Grid-Tied photovoltaic (PV) inverters. These include implementations such as the H5, H6, and HERIC topologies, among others. In this paper, a new full bridge topology synthesis method, called the MN synthesis method, is proposed. The MN method introduces two criteria that can be used to synthesize...
In this paper a new full bridge topology called the two-phase non-isolated full bridge (NFB) is introduced. The proposed two-phase NFB can handle the same power as two parallel one-phase NFBs, but with less MOSFETs, better efficiency and lower cost. To demonstrate the advantages of the new topology, two prototypes are built on a 12 layer 2 oz PCB board, one with four inductors, the other with three...
In this paper a new topology is introduced to solve the narrow duty cycle and hard switching problems of the interleaved Buck converter voltage regulator module. The new topology is called the non-isolated full bridge (NFB). In comparison to the interleaved Buck converter, it operates with a significantly wider duty cycle and can achieve zero voltage switching at turn on for the high side MOSFETs...
In this paper a new non-isolated full bridge topology is introduced. The primary side of this topology is a full bridge; however, the input voltage ground of the conventional full bridge is connected directly to the positive point of the output and not connected to the input ground. In this arrangement, the input current flows directly to the load without going through the transformer. The secondary...
The duty cycle of conventional multi-phase buck converters becomes extremely small as the output voltage becomes lower and lower. This is a severe challenge with the switching frequency goes up. This paper introduces a non-isolated half bridge converter which can extend the duty cycle to a favorable range. Thus, the converter will have symmetrical dynamic response ability. The switching loss will...
