    This paper presents design and implementation of a Integrated boost-flyback converter (IBFC). Operation of the IBFC is described and its key voltage and current equations are given. The practical design of a 96W, 12V-to-48V, IBFC is demonstrated. Experiment on the prototype IBFC shows that it operates with good output voltage regulation and achieves the highest efficiency of 87%.

    In recent years, an application of a piezoelectric transducer to harvest energy from ambient vibrations has been a subject of intense research. As the material technology advances, the amount of energy being able to produce by the transducer continues to increase. This paper presents an experimental study of a vibration based energy harvesting system for an RFID module. The system consists of a piezoelectric transducer, a power management circuit based on a buck converter, and an RFID module. The transducer converts mechanical movement produced by a finger press into a voltage to charge an input capacitor. The buck converter then converts the input capacitor voltage into a stable DC output voltage to power the RFID module. Experimental results are presented to validate the performance of the proposed energy harvesting system.

    This paper presents analysis, design and experimentation of a Quadratic Boost Converter (QBC). Operation of the QBC is analyzed, leading to mathematical expressions that can be used to design the converter. Based on the derived analytical expressions, a 100W, 12V-to-48V, QBC converter is designed and built. Experiment shows that the prototyped converter operates satisfactorily throughout its operating range and achieves the highest efficiency of 83%.
