Study of a High-Efficient Wide-Bandgap DC-DC Power Converter for Solar Power Integration

STUDY OF A HIGH-EFFICIENT WIDE-BANDGAP DC-DC POWER CONVERTER FOR SOLAR POWER INTEGRATION Yashwanth Bezawada Old Dominion University, 2017 Director: Dr. Yucheng Zhang This research focuses on the design and analysis of a Boost cascaded Buck-Boost (BoCBB) power converter with super high efficiency in electric power conversion. The BoCBB power converter is based on emerging wide-bandgap silicon-ca...

A New Power Management Approach for PV-Wind-Fuel Cell Hybrid System in Hybrid AC-DC Microgrid Configuration

The hybrid AC-DC microgrid (HMG) architecture has the merits of both DC and AC coupled structures. Microgrids are subject to intermittence when the renewable sources are used. In the HMG, since power fluctuations occur on both subgrids due to varying load and unpredictable power generation from renewable sources, proper voltage and frequency regulation is the critical issue. This article propos...

Nonlinear Control for Bidirectional Power Converter in a dc Microgrid

Some comparative studies of several nonlinear control techniques applied to dc-dc power converters are developed in this paper, like for instance the Immersion & Invariance, Passivity-Based Control, Feedback Linearization and the Sliding-Mode Control. All these different control strategies are used to drive dc-dc power converters in a dc microgrid. The load, modeled as a Constant Power Load typ...

Dc- Dc Boost Converter for Solar Power Application

A Conventional Boost Converter is not capable for obtain a high voltage gain even extreme duty cycle maintain the triggering circuit diagram. In order to increase the voltage gain for the new Boost converter from the solar power application. In this paper boost converter specialty is achieved 10 times that of input voltage and more than 10 times of input voltages is possible from output side by...
