Effect of non-ideal on the design and efficiency of high voltage gain transformerless DC-DC converter topology

A High Voltage Gain Transformerless (HVGT) DC-DC converter is analyzed in a non-ideal state. The parasitic effect in passive components and semiconductor device are considered. The effect of these parasitic on the various design issues of several DC-DC converters is also studied. Firstly, the non-ideal steady-state analysis of the converter was done. During analysis, the winding resistance of the inductor and voltage drop of a semiconductor device are considered. Afterward, a digital control system was designed, and the converter was simulated using MATLAB/Simulink. After the converter circuit was manufactured, the controller was embedded in a digital signal processor-based microcontroller and the system was tested for variable load and variable input voltage conditions, and its performance was examined.
