“…Nonisolated multiport converters are usually used in the applications where a low voltage regulation ratio is required [4], [5]. In contrast, in the applications requiring a high voltage regulation ratio, isolated converters which contains a transformer is preferred [6]- [8]. The currently used isolated multiport topologies include the isolated full-bridge converter [6], which uses four controllable power switches for each source, the isolated half-bridge converter [9], which uses two switches for each source, and the isolated single-switch converter [10], which only uses one switch for each source.…”

Abstract-This paper proposes a new isolated, three-port, bidirectional, DC-DC converter for simultaneous power management of multiple energy sources. The proposed converter has the advantage of using the least number of switches and soft switching for the main switch, which is realized by using a LCL-resonant circuit. The converter is capable of interfacing sources of different voltage-current characteristics with a load and/or a DC microgrid. The proposed converter is constructed for simultaneous power management of a photovoltaic (PV) panel, a rechargeable battery, and a load. Simulation and experimental results show that the proposed converter is capable of maximum power point tracking control for the PV panel when there is solar radiation and controlling the charge and discharge of the battery when there is surplus energy and power deficiency with respect to the load, respectively.

“…Especially, its magnetic components such as the boost inductor and isolation transformer are a primary factor of increasing the size and cost [1]. Whereas, the singlestage PFC converter has a simple structure, and can provide the both isolation and output regulation through single power conversion stage [2]- [3]. However, since its regulation performance and input power factor are worse than those of the two-stage approach, its applications are limited [1].…”

This paper deals with an integrated magnetic design for the boost PFC and flyback converters with single magnetic core. A phase-shifted PWM technique is proposed to reduce the maximum flux density of the shared magnetic paths of the core. The proposed technique provides the advantage of minimizing the cross sectional area of the shared core limbs required to avoid the flux saturation, which results in the size reduction and cost down of the magnetic core. The principle and operation of the IM design and proposed PWM technique are presented for the boost PFC and flyback converters with single magnetic core. The simulation and experimental results are provided to verify the effectiveness of the proposed method.I.

“…Some of them have certain limitations. For example, the duty cycle of the converter in [9] should be set larger than 50% even in the start-up mode. The inductor-fed boost converter in [10] has a high voltage stress across the switch when it is turned off, and an additional voltage clamp circuit is required.…”

Abstract-Isolated converters are desirable in the DC-DC power conversion applications where isolation and/or a large voltage step-up gain is needed. Traditional isolated DC-DC converters either utilize many switches to achieve high efficiency or use few switches which result in low efficiency. This paper proposes a new single-switch isolated DC-DC converter with a LCL-resonant circuit. The proposed isolated DC-DC converter has the advantages of not only using the least number of (i.e., one) switch, but also achieving zero-current switching (ZCS) and zero-voltage switching (ZVS) when the switch is turned on and off, respectively. Experimental results are provided to validate the theoretical analysis and simulation. The proposed converter has achieved the maximum efficiency of 93.5%, which is higher than the corresponding hardswitching converter with a similar topology.
