In This paper, a Bidirectional DC-DC converter also known as dual active bridge (DAB) dc–dc converter is presented. A Z-source with bidirectional dc–dc converter by reducing the switching count by adding passive elements has improved the output voltage level, when compared with the traditional bidirectional dc–dc converter. The proposed converter has a wider regulation range of voltage. The fully bridge symmetrical circuit configuration, is neither a high-voltage side nor a low-voltage side in the circuit structure, and the sources connected to the dc side of each H-bridge circuit with voltage sources and current sources. This method can reduce current stress and improves the system efficiency. Simulation results are shown by using MATLAB software.
