A Hybrid Switching Modulation of Isolated Bidirectional DC-DC Converter for Energy Storage System in DC Microgrid

A Bidirectional DC-DC Convreter with Zero Voltage Switching Capability for Energy Storage Application

In this paper, a bidirectional DC-DC converter with high power density for energy storage application is proposed. The presented converter provides power transfer in both directions only with adjusting phase shift angle. Zero voltage switching (ZVS) in both turn on and turn off moments of all switches is the major capability of the converter that makes it suitable for high power applications. Z...

A Non Isolated Bidirectional Dc-dc Converter with Soft Switching

Power electronic converter systems for applications such as telecom, automotive, and space can have dc voltage buses that are backed up with batteries or super-capacitors. These batteries or super-capacitors are connected to the buses with bidirectional dc–dc converters which allow them to discharged or charged, depending on the operating conditions. Bidirectional dc–dc converters may be isolat...

Isolated Bidirectional DC-DC Converter for Hybrid Electric Vehicle Applications

Hybrid electric vehicles (HEVs) offer many advantages, such as high fuel economy, low emissions, and silent operation. In HEVs, there are two or more different voltage buses for different purposes of the vehicle operation. There are needs of galvanically isolated bidirectional DC-DC converter to link different DC voltage bus and transfer energy back and forth. For example, on of the DC-DC conve...

A Bidirectional Nonisolated Multi-Input DC-DC Converter for Hybrid Energy Storage Systems in Electric Vehicles

Sliding Mode Control of a Bidirectional Buck/Boost DC-DC Converter with Constant Switching Frequency

In this paper, sliding mode control (SMC) for a bidirectional buck/boost DC-DC converter (BDC) with constant frequency in continuous conduction mode (CCM) is discussed. Since the converter is a high-order converter, the reduced-order sliding manifold is exploited. Because of right-half-plan zero (RHPZ) in the converter’s duty ratio to output voltage transfer function, sliding mode current...
