Development of Effective Analysis of a High Gain Triad Input Dual Output DC-DC Converter for Microgrid Application

This manuscript discusses the effective analysis of new Triad Input Dual Output (TIDO) high gain DC-DC converter preferred for microgrid applications. The TIDO converter enables the incorporation of multiple renewable energy power generators with DC output at the input and provides dual output ports with different voltage levels. The TIDO converter features high voltage gain, multiple ports with bidirectional facility, reduced voltage, current stress, and better operating efficiency. The circuit configuration of the proposed converter was detailed with steady state analysis, relevant voltage equations, and waveforms. The effective analysis includes component stress analysis, loss analysis, and comparative analysis of the TIDO converter. The proposed high gain TIDO DC-DC converter is simulated using PSIM software. The results validate the voltage across various components and currents through the components with the high grain output voltages for effective steady state operating performance of the presented converter. Finally, a 15.45 kW, 1000 V~ 500 V DC-DC converter was analyzed effectively for medium voltage DC (MVDC) distribution or hybrid electric vehicle application.
