A transformerless multiple-port DC-DC converter for energy harvesting and dispatching

摘要: Multiple-port converters (MPCs) have been identified as a cost-effective approach for energy harvesting and dispatching in hybrid power systems. Compared with relatively complex set-up of single-input single-output linked at common dc bus to exchange power, the MPCs possess promising features fewer components, higher density centralized control. This paper proposes transformerless MPC that transfers between different sources loads minimal number conversion steps. The steady-state analysis dynamic modeling proposed are introduced detail. output voltage regulation flow control can be achieved simultaneously by multivariable Detailed switch simulation average model presented verify effectiveness MPC.
