ZVC Based Bidirectional DC-DC Converter for Multiport RES Applications

01 Jan 2017-pp 483-492
Abstract: This article proposes an advanced converter technique that integrates all major ports in that double unidirectional source port, one battery port for (charging and discharging), and a single ideal power consumption port (load port). A new multi-port DC-DC power converter is developed when added to a pair of semi conducting switches and a pair of PN junction diodes to a basic half bridge (HB) converter circuit. Zero voltage conduction (ZVC) is performed on every major switch. This technique is implemented for savings huge number of component count and to reduced losses obtained from renewable energy applications.

Abstract: This paper presents a new zero-voltage-switching (ZVS) bidirectional dc-dc converter. Compared to the traditional full and half bridge bidirectional dc-dc converters for the similar applications, the new topology has the advantages of simple circuit topology with no total device rating (TDR) penalty, soft-switching implementation without additional devices, high efficiency and simple control. These advantages make the new converter promising for medium and high power applications especially for auxiliary power supply in fuel cell vehicles and power generation where the high power density, low cost, lightweight and high reliability power converters are required. The operating principle, theoretical analysis, and design guidelines are provided in this paper. The simulation and the experimental verifications are also presented.

Abstract: An isolated three-port bidirectional dc-dc converter composed of three full-bridge cells and a high-frequency transformer is proposed in this paper. Besides the phase shift control managing the power flow between the ports, utilization of the duty cycle control for optimizing the system behavior is discussed and the control laws ensuring the minimum overall system losses are studied. Furthermore, the dynamic analysis and associated control design are presented. A control-oriented converter model is developed and the Bode plots of the control-output transfer functions are given. A control strategy with the decoupled power flow management is implemented to obtain fast dynamic response. Finally, a 1.5 kW prototype has been built to verify all theoretical considerations. The proposed topology and control is particularly relevant to multiple voltage electrical systems in hybrid electric vehicles and renewable energy generation systems.

Abstract: A new topology for multiple energy source conversion is presented. The topology is capable of interfacing sources of different voltage-current characteristics to a common load, while achieving a low part count. A fixed frequency switching strategy is investigated and the resulting operating modes are analyzed. The analysis is verified by experimentation. The results show that the converter is an enabling technology for power diversification and optimization.

Abstract: In the zero-emission electric power generation system, a multiple-input DC-DC converter is useful to obtain the regulated output voltage from several input power sources such as a solar array, wind generator, fuel cell, and so forth. A new multiple-input DC-DC converter is proposed and analyzed. As a result, the static and dynamic characteristics are clarified theoretically, and the results are confirmed by experiment.

Abstract: In this letter, a new multiple-input (MI) hybrid energy conversion topology is presented. The proposed topology is capable of energy diversification among different energy sources with different voltage-current characteristics while achieving low part number and bidirectional operational. Compared to the earlier MI buck-boost converter, the proposed topology provides positive output voltage without any additional transformer, is capable of bidirectional operation, and has the capability of operating in buck, boost, and buck-boost modes separately. A fixed-frequency switching strategy is considered, and analytical analyses, detailed device-level simulation, and experimental results are presented.
