Rev. Abstract The most recent version (C2MTM) of Silicon Carbide (SiC) devices is used in a Zero Voltage Switching (ZVS) converter application. A 1200V, 160mohm SiC MOSFET from Cree Inc. is used to design a high-frequency ZVS LLC resonant fullbridge (FB) DC/DC converter. With the outstanding advantages of SiC MOSFET, which has lower junction capacitance and low-on-state resistor compared to a s...

Among the many advantages that resonant power conversion has over conventionally adopted pulsewidth modulation include a low electromagnetic interference, low switching losses, small volume, and light weight of components due to a high switching frequency, high efficiency, and low reverse recovery losses in diodes owing to a low di/dt at switching instant. This work presents a novel loaded-reso...

Renewable energy generation systems, based on photovoltaic sources, currently represent the most suitable solution, for low power levels, to reduce the energy consumption produced by oil and gas. Moreover, they are becoming more and more attractive as the price per watt of the photovoltaic modules is decreasing. However, the conversion efficiency of commercial photovoltaic modules is still rath...

Using PSPICE a resonant dc-dc converters operating at constant frequency was simulated. The paper concentrates on the working of a half bridge topology employing ZVS techniques. The operation of converter with LC filter in the output is discussed. The design and fabrication was done on a 5V, 50W converter using MOSFET to validate the performance of the converter. The converter has illustrated l...

An electric vehicle (EV), otherwise called as an electric drive vehicle uses one or more electric motors or traction motors to create the driving force needed for motion. Considering the power supply for vehicle computer and electronics, battery and DC-DC converter is required. To achieve the required voltage levels, power converters and inductances are required. Resonant converters are popular...
