This book helps the researchers and industrialists working on power electronic converters for renewable source integration. To design a hybrid renewable energy source (RES) system, different power electronic converter (PEC) topologies are discussed and highlighted in this book. Among all, non-isolated multi input DC-DC power converters are extensively utilized for its simple structure and it does not require a high frequency transformer. In this book, different power electronic converters are integrated together by sharing and merging power converter components between the DC-DC converters to develop a hybrid power converter. A hybrid system necessitates an individual maximum power point tracking (MPPT) control algorithm to track the maximum power point (MPP) from the high penetration of RES. As the number of control algorithms increases, this can escalate the system intricacy and its implementation. To overcome these flaws, a single MPPT control algorithms are discussed and highlighted in this book for extracting MPP concurrently. By going through this book one can easily understand the hybrid renewable energy system and role of power electronics in renewable energy system.
