Simulation and Performance Analysis of a DC-DC Converter with Enhanced Voltage Gain, Wide Input Voltage Variations, and Unified Ground Configuration

An effective DC-DC converter for fuel cell vehicles should possess the parameters such as efficiency, compactness, and voltage levels. Traditional converters like the two-level, three-level, and cascaded boost ones can't quite meet these needs. So, in this paper, we've developed a new converter topology. This converter uses switched capacitors and inductors and doesn't have any electrical isolation. The converter can achieve high voltage gain, can operate at wide range of input voltages, doesn't have high voltage stress on its components, and uses a common ground setup. PSIM software is used to simulate our converter, to test its performance. The proposed converter delivers 400V and 400W in terms of output voltage and power ratings, respectively. And, based on our simulations, the proposed converter topology works well with fuel cell based electric vehicles.
