A Z-source DC-DC dual output converter
A Z-source dc-dc dual output converter is presented in this paper, which has inherent behavior of two conventional converters, i.e. Z-source dc-dc converter and buck-boost converter. The proposed converter is synthesized using Z-source network and integrated dual output converter (IDOC). In comparison with conventional topologies, the proposed converter uses lesser number of components and hence it is more reliable. The proposed converter exhibits a high voltage gain, while boosting, over the IDOC topology. The operating principle is introduced first and then steady-state, small-signal analysis is presented. Converter parameters design equations are formulated and then comparison with other converters is presented. The dynamic behavior of the converter is analyzed through its control-to-output transfer functions. Simulation results validates the effectiveness of theoretical analysis of proposed converter.
