“…This paper refer above literature develops a high-efficiency high-frequency and high-powerdensity DC-DC power module for China "Fuxing" high-speed EMU. American's Bel-fuse (0RQB-C5W24R-1839HZ), the current most advanced power module as a reference standard, which adopt metal-oxide-semiconductor field-effect transistor as switching devices, use single level topology architecture, the size is a quarter standard package, the peak efficiency can reach 95% [26]. To make a fair comparison, taking the current most advanced power module as the standard, in the same package and same size of the case, using two-level topology structure, and gallium nitride as a switching device develop a power module [8][9][10][11][12][13][14][15].…”

This paper develops a railway power module with wide range voltage (dc 60—dc 160 V) input and constant voltage output (24 V/10 A) . The power module adopts a two‐stage topology structure to realize voltage conversion. Use the most advanced GaN (gallium nitride) as the main power switching devices. The first stage circuit architecture uses a two‐phase interleaved buck converter convert the wide range input voltage into a constant intermediate bus voltage (48 V) through closed‐loop control, and then the LLC resonant converter converts the intermediate bus voltage (dc 48 V) into a constant output voltage (dc 24 V) through open‐loop control, and realize the primary side and secondary side dc 3000 V electrical isolation. This article from the circuit topology, the power devices selection, buck converter magnetic integrated coupling inductance design, planar magnetic integration LLC resonant transformer optimization design has carried on the detailed discuss and analysis. All circuits are integrated in a standard quarter power brick module, the final prototype can reach 96.1% peak efficiency, the power density can reach 185 W/in.3.

“…Therefore, it is necessary to have a capacitor in parallel at the input of the CDR to decouple both current sources as in [92] and [91]. In [112] and [113], an inverse coupled current double rectifier (ICCDR) for LLC resonant converters is proposed, which is also compatible in the S-S WPT system [114].…”

Mazaheri and so on. I am grateful to have shared this important phase of my life with you in Madrid. To all the laughters, beers, dinners, Wednesday movies and seminars.Finally, I would like to dedicate this thesis to my parents, Tongxi Shi and Xianhua Wei. Your never-ending love and unconditional support have always given me one more reason for being a better version of myself. In every step forward of my life, I have owed them a great debt of thanks that cannot be expressed in any words. Also, I would like to thank my two elder sisters for taking care of our parents while I am staying far away from home, which helps me stay focused on this thesis.
