In renewable energy systems such as the PV system, the batteries are connected to ensure a stable supply of energy. Therefore, the bi-directional power conditioners have a key role in renewable power systems. In this paper, bi-directional LLC resonant converter as the power conditioner is proposed. The ac analysis and operating characteristics of bi-directional LLC resonant converter are investigated.
This paper presents the design consideration of a low-profile LLC resonant converter using two flat transformers. The trend toward high power density, high efficiency, and low profile in power supplies has exposed a number of limitations in the use of magnetic component structures. The LLC resonant converter can be operated at a high switching frequency with high efficiency because the switching loss...

This paper presents the design of two flat transformers in LLC resonant converter. The trend toward high power density, high efficiency, and low profile in power supplies has exposed a number of limitations in the use of magnetic component structures. In the LLC resonant converter, the switching loss is reduced by soft-switching. Therefore, LLC resonant converter can be operated at high switching...
Nowadays high power density, high performance, and high efficiency converters become a hot issue of the PDP TV. For meeting requirements, the design and implementation of LLC resonant converter using low-profile magnetic component for PDP is proposed in this paper. In order to use a flat transformer, it is necessary to operate the converter at high switching frequency. In the LLC resonant converter,...
The trend in Plasma Display Panel (PDP) TV is towards the thinner thickness, lighter weight, and fan-less system. For achieve this goal, it is desired advanced power conversion technique to implement a low-profile power supply for PDP. As PDP power module, LLC resonant converter is widely used because it can achieve both high efficiency and reliability. To achieve a low-profile circuit configuration,...
Low-profile, high efficiency power supply is today's industry trend for Plasma Display Panel (PDP) application system. Transformer is the major challenge and bottleneck for achieving low-profile, high power density converter. Generally, it is necessary for low-profile converter to operate it at high switching frequency. However, it is very difficult to design converter using flat magnetic component...
