Modelling and Real-time Validation of a Two–input High–gain DC–DC Converter with a Reduced Number of Switches
Abstract
Power electronic converters play a major role in different applications such as power generation, transmission, distribution, and emerging electric vehicle (EV) technology. Among different types of power electronic converters, DC-DC converters are taking a crucial responsibility in renewable energy resources-based power generation (RERPG) and EV applications, as there is a huge variation between output and input voltage levels. In this article, the operation and modeling of a dual-input high-gain DC–DC converter with a reduced number of switching elements are discussed. The diode–capacitor voltage multiplier (DCVM) cells are utilized in the suggested converter to achieve the ultra-high gain. Because of the lower number of power semiconductor switches and better design, the designed converter exhibits 97.09% efficiency at the selected duty cycle and power rating. To validate the design, a hardware setup is also produced and tested effectively with OPAL-RT OP5700 real-time simulator (Hardware-in-the-loop). By using this converter, RERPG, and EV systems gains the advantage of lower number of switches, high gain, simple design, minimal voltage stress, and higher efficiency.
