Abstract:

— The input-parallel-output-parallel (IPOP) dual-active-bridge (DAB) converter is a popular solution to be used as a solid-state-transformer (SST) to increase current capacity for its advantages, including bidirectional power flow, soft switching, and high efficiency. To reduce circulating and turn-off currents under single-phase-shift (SPS) control, an IPOP DAB converter with a modulated coupled inductor and the optimized modulation trajectory are proposed in this article. Compared with the previous modulated coupled inductor solutions, the phase-shift angle between two modules is controlled by PWM signals from 0◦ to 180◦, instead of just working at two fixed values (0◦ and 180◦). Based on the derived model of the modulated coupled inductor and analysis of converter working modes, the relationship between the two phase-shift angles and the current stress of the converter is analyzed in depth. Consequently, an optimized modulation trajectory is also proposed to achieve low turnoff current and rms current for IPOP DAB converters used for SST applications. The parameters design, including leakage inductance and coupling coefficient, is introduced. A 250-kHz, 400-/400-V, 2000-W IPOP DAB prototype is built to verify the effectiveness of the proposed solution. © 2023 IEEE.
