Conducted Emission Mitigation for Solid-State Transformer using Modulation and Multiple Configuration Techniques
Year: 2025
Type: conference-paper
Abstract: Solid-state transformers have several advantages over conventional 50 Hz transformers. However, the high switching speed of power electronic devices generates electromagnetic interference (EMI) that can cause malfunction. Conducted emission mitigation techniques for solid-state transformers using appropriate modulations and configurations in the QSPICE simulator are analysed in time and frequency domains. Common-mode (CM) emission and reactive power can be improved using proper modulation and configuration techniques for single and multiple solid-state transformers. The single-phase shift modulation has the lowest CM emission and the highest reactive power. In contrast, the triple-phase shift modulation demonstrates the highest CM emission and the lowest reactive power among the various modulation strategies. The CM emission of single and multiple solidstate transformers with dV/dt cancellation capability is below the IEC 62041-2020 standard limits.
