An experimental study of a zero voltage switching SiC boost converter with an active snubber network
- This paper presents a quasi-resonant, zero voltage switching (ZVS) SiC boost converter for an output power of up to 10 kW. The converter is realized with an easily controllable active snubber network that allows a reduction of switching losses by minimizing the voltage stress applied to the active switch. With this approach, an increase of the switching frequency is possible, allowing a reduction of the system size. Experiments show a maximum converter efficiency up to 99.2% for a switching frequency of 100 kHz. A second version of the converter enables a further size reduction by increasing the switching frequency to 300 kHz while still reaching a high efficiency up to 98.4 %.
