    • Dynamic phase angle and dead-time compensation for high-efficiency dual active bridge converters 

      Palmer, D.; Musiiwa, P. B.; Kapuya, E. T.; Musademba, D. (БНТУ, 2025)
      Dual Active Bridge (DAB) DC-DC converters have emerged as a critical technology in high-power applications requiring bidirectional energy transfer and galvanic isolation, particularly in electric vehicle (EV) charging systems and renewable energy integration. The research demonstrates that intelligent dead time management significantly reduces switching losses while maintaining ...

    • Effects of dead-time in dual active bridge 

      Machongwe, T.; Musiiwa, P. B.; Mutamba, C. T.; Makusha, D. T.; Kapuya, E. T.; Musademba, D. (БНТУ, 2025)
      The article explores the effect of dead-time in the operation of a Dual Active Bridge (DAB). DABs consist of high-speed switching devices (usually MOSFETS) as the main architecture component. The switches turn off and on at frequencies greater than 50 MHz. During this switching period, switches change from their low state to high state. If the fall time is greater than the time ...

    • Effects of phase shifting in dual active bridge (DAB) converters 

      Mutamba, C. T.; Musiiwa, P. B.; Machongwe, T.; Chimonyo, K. B.; Kapuya, E. T.; Musademba, D. (БНТУ, 2025)
      This paper analyses the effects of phase shifting in Dual Active Bridge (DAB) converters, which are widely applied in electric vehicle chargers, renewable integration, and solid-state transformers. Its symmetrical topology, comprising two full-bridge converters linked by a high frequency transformer and controlled through phase-shift modulation, enables seamless power flow in ...

    • Phase angle and dead time in dual active bridge designs for electric vehicles and solar charge inverters 

      Nyambayo, T. C.; Musiiwa, P. B.; Kapuya, E. T.; Musademba, D. (БНТУ, 2025)
      This paper presents a detailed analytical and simulation centered study of two widely used timing methods / controls in the implementation of Dual Active Bridge (DAB), that is Dead Time and Phase Angle. In this research paper, we will delve deeper into trying to have a well-informed understanding on the impact and relationship between the switching times experienced during the ...
