    • 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 ...
