“…However, the switching of the secondary‐side switch requires additional phase detection chip to achieve synchronous rectification, which undoubtedly brings potential stability problems. In Song et al, 12 isolated dual active bridge, and Han and Corradini, 13 non‐isolated dual active bridge topologies, the dual‐bridge series resonant converter (DBSRC) replaces the inductor in DAB with a resonant slot, and the resonant capacitor plays the role of isolating the DC component while participating in resonance, and the sinusoidal current also reduces the switching losses. But the DBSRC, like the DAB converter, requires complex control in power transfer.…”

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%.

Increasing the switching frequency helps optimize the performance of resonant DC-DC converters and reduces the size of resonant components, but it also increases the switching losses. To address the challenge of achieving soft switching in the medium to low power range, this paper proposes a new control strategy. In this paper, it achieves a wide range of Zero Voltage Switching (ZVS). It combines Variable Frequency Modulation (VFM) and Phase Shift Modulation (PSM), utilizing Minimum Current Trajectory (MCT) control to reduce the system’s conduction losses. Besides, VFM is used to extend the ZVS range and reduce switching losses.
