Resumo: This work presents the study in steady-state and dynamic regime of the modified multiport current fed Push–Pull dc-dc converter, obtained from the Boost DC-DC converter based on the Three-State Switching Cell (3SSC). For the proposed converter, a qualitative and quantitative analysis was performed, operating with a duty cycle value (D> 0,5). Such analysis was performed in continuous conduction mode (CCM). The topological modification relative to the Boost DC DC converter based on 3SSC, allows the obtaining of several isolated DC- output voltages from a single voltage source, to supply cascaded H-bridge and NPC inverters. The presence of 3SSC allows high voltage gain to the converter, and in addition the switching losses of the main switches are sent to the output. n order to verify the principle of operation of the converter, computer simulations were performed in closed loop with input voltage of 42V, output voltage of 800V and output power. The tests in steady state and in dynamic regime, present a good performance of the topology, thus validating the theoretical studyThis work presents the study in steady-state and dynamic regime of the modified multiport current fed Push–Pull dc-dc converter, obtained from the Boost DC-DC converter based on the Three-State Switching Cell (3SSC).
