    • Control of DC-capacitor peak voltage in reduced capacitance single-phase STATCOM 

      Isobe, Takanori; Zhang, Long; Tadano, Hiroshi; Suul, Jon Are Wold; Molinas Cabrera, Maria Marta (Chapter, 2016)
      This paper discusses the design and control of a single-phase STATCOM with reduced dc capacitance. It is first demonstrated how operation with reduced dc capacitance and large dc voltage oscillations can be possible without ...

    • Impedance scanning with chirps for single-phase converters 

      Føyen, Sjur; Zhang, Chen; Molinas Cabrera, Maria Marta; Fosso, Olav B; Isobe, Takanori (Chapter, 2022)
      Impedance scanning of single-phase AC-DC converters is challenging due to frequency couplings, which map one injection frequency to a multiple of output frequencies. Single-tone injections are often preferred over wideband ...
