Abstract
Various examples are provided for soft switching solid state transformers and converters, and their operation and application. In one example, a soft switching solid state power transformer includes a high frequency (HF) transformer; first and second auxiliary resonant circuits coupled to the HF transformer; and first and second current-source inverter (CSI) bridges coupled to the corresponding first auxiliary resonant circuits. The first and second CSI bridges include reverse blocking switch assemblies that conduct current in one direction and block voltage in both directions. In another example, a reactive power compensator includes a high frequency (HF) transformer, first, second and third auxiliary resonant circuits coupled to the HF transformer, and first, second and third current-source inverter (CSI) bridges coupled to the corresponding first auxiliary resonant circuits. In another example, a converter includes an auxiliary resonant circuit coupled across an inductor and first and second CSI bridges coupled across the inductor.
