Mosfet cross conduction
WebApr 10, 2024 · Achieving low conduction loss and good channel mobility is crucial for SiC MOSFETs. However, basic planar SiC MOSFETs provide challenges due to their high density of interface traps and significant gate-to-drain capacitance. In order to enhance the reverse recovery property of the device, a Schottky barrier diode (SBD) was added to the … WebJun 29, 2016 · This means, with the triple charge pump feature of DRV8305, the MOSFET conduction loss can be reduced by 25-30% at lower DC bus voltage (5V) and hence higher efficiency. To reduce conduction losses, you must select both a MOSFET with the lowest R DS_ON and a proper gate driver that can provide the maximum gate-drive voltage for all …
