    A fixed frequency ZVS integrated boost dual three-phase bridge DC-DC LCL-type series resonant converter for large power applications
    (Institute of Electrical and Electronics Engineers Inc., 2017) Nagendrappa, H.; Bhat, A.K.S.
    The design of a converter as an example of a high power (>10 kW), fixed frequency controlled three-phase DC-DC LCL-type series resonant converter (SRC) with integrated boost function is described. The specifications of the converter are chosen to match the rating of a linear generator (LG) used in wave energy generation application. The performance of the designed converter has been verified by using PSIM simulation software. The zero-voltage-switching (ZVS) of all the switches is accomplished by designing the converter to operate in the lagging pf mode for a wide input voltage and load variations. Theoretical and simulation results have been compared and presented in the form of a table. Power loss break-down analysis of the designed converter has been done and the summary of results is presented. © 2017 IEEE.

    A 10 kW ZVS integrated boost dual three-phase bridge DC–DC resonant converter for a linear generator-based wave-energy system: Design and simulation
    (MDPI AG indexing@mdpi.com, 2019) Nagendrappa, N.; Bhat, A.K.S.
    The design and performance analysis of a 10 kW three-phase DC–DC LCL-type resonant converter having a built-in boost function were carried out. This high-power converter is proposed for its application in grid-interfacing a linear generator (LG)-based wave-energy system. Fixed-frequency control is used, and the converter was designed to operate with a lagging power factor. It is shown that all switches turn on with zero-voltage switching (ZVS) for wide input voltage and load variations. This results in reduced switching losses and stresses, which is very important in large-power applications. The performance of the converter was studied through PSIM simulation software. Theoretical and simulation results are presented for comparison. Power-loss break-down analysis of the designed converter was carried out and the summary of results is presented. © 2019 by the authors. Licensee MDPI, Basel, Switzerland.
