This paper provides a systematic survey on the topology morphing control techniques used in the galvanically isolated dc-dc converters. Existing techniques are broadly categorized based on the part where a converter changes its topology: at the input side, at the output side, and the advanced techniques that cannot be categorized in the first two groups. The techniques span from the simple reconfiguration between the full-and half-bridge switching cells similar to the conventional power supplies with universal ac input to the advanced multi-track topology and reconfigurable resonant tanks. In addition, the described variety of application examples proves the wide application range and versatility of the topology morphing control. These include fault tolerance, efficiency curve flattening, input voltage range extension, and other properties. Hence, this article provides a single comprehensive source for researchers and engineers willing to enter the topic of topology morphing control.INDEX TERMS Galvanically isolated DC-DC power converter, topology morphing control, series resonant converters.

“…Le Anh Dao et al 7 extend the gain range by increasing the number of resonant slots and changing the primary circuit structure, and Yifeng et al 8 extend the gain range by adding switched capacitors to the resonant slots. Mehdi et al 9 replace the secondary full‐bridge rectifier with a voltage‐doubling structure, and Bakeer et al 10 add bidirectional switches to the voltage‐doubling rectifier, thereby expanding the output voltage range at a fixed frequency. All of these structures require additional components and more complex control methods to regulate the voltage, increasing system complexity and decreasing system reliability.…”

This paper proposes a secondary‐side semi‐active series resonant converter with hybrid control. Compared with the traditional series resonant converter (SRC), the converter only replaces two diodes with metal oxide semiconductor field effect transistors (MOSFETs) on the secondary side of the transformer, without adding any auxiliary components. By employing hybrid modulation scheme, the proposed converter can achieve a wide output voltage range in a narrow switching frequency range with high efficiency and has excellent soft‐switching performance. Due to the large magnetizing inductor and narrow switching frequency range, the proposed converter can achieve energy delivery with high efficiency and high power density. This paper provides a detailed introduction to the working principle, circuit characteristics, and design process of the converter. Finally, a 3.3 kW SiC‐based experimental prototype with 400 V input, 250–430 V output, and a switching frequency of 120–140 kHz is built to verify the theoretical analysis, and the peak efficiency reaches 97.82%.
