| Sumario: | In this paper a pure bidirectional switched capacitor DC-DC converter is proposed. This structure of the proposed converter allows parallel and cascade modular connection, which allows its use in different applications. The basic cell of the proposed topology is evaluated in detail in this paper. For this, characteristics of the principle of operation for step-up and step-down mode, voltage gain, voltage and current stresses, comparative evaluations with similar topologies are presented. To validate the effectiveness of the proposed converter, a prototype was built in laboratory and it achieves a 94.8 % peak efficiency with a switching frequency equal to 20 kHz. |
