What is MOSFET VDS ringing?

2024.10.22 HNST views: 23
MOSFET

VDS ringing refers to the phenomenon where VDS (DC source drain voltage) oscillates when using silicon carbide MOSFETs. This is due to the special working principle of MOSFET, as MOSFET is a switching device that has the ability to change between on and off states.

When MOSFET is in the on state, its VDS may oscillate, leading to circuit instability. This is because the on resistance of the MOSFET that is turned on changes with the current, resulting in the ringing of VDS.

To avoid VDS ringing problems, it is usually necessary to use some voltage stabilization circuits to ensure the stability of MOSFET VDS. In addition, the special operating characteristics of MOSFETs need to be considered when designing circuits to ensure the stability of the circuit.

Introduction to SiC Silicon Carbide MOSFET Devices SiC devices are a new type of silicon-based MOSFET, especially SiC power devices with higher switching speed and wider output frequency. SiC power chips are mainly composed of MOSFETs and PN junctions.
Why does high negative pressure in SiC MOS affect threshold drift The threshold drift of SiC MOSFET is affected by negative pressure because this device has a high leakage current, which reduces the difference between the control terminal voltage and the source terminal voltage, thereby affecting the switching performance of MOSFET. In addition, high negative pressure may also cause MOSFETs to enter rupture mode and trigger other adverse effects.
The Development Trend of High Voltage SiC MOSFET The research on high-voltage SiC MOSFETs is gradually deepening, mainly focusing on the design, preparation, and detection of high-voltage SiC MOSFETs. In the past two years, Sic Mosfet has broken through the peak tunneling voltage of 2600V, with crystal surface insulation characteristics as high as 200MV • cm-1, and static performance reaching 500A/1700V for a single chip in a half bridge topology. It can also support constant current and constant voltage regulator operation. In addition, there are SiC Mosfets designed for solid-state dye solar energy to meet the needs of these applications.
5 important techniques for selecting gallium nitride (SiC) MOSFETs To prove that your choice of SiC as the preferred power semiconductor for switch mode design is correct, please consider the following prominent features. Compared to standard or super junction MOSFETs or even IGBTs, SiC devices can operate at higher voltages, frequencies, and temperatures. Most of the power loss of other devices does not exist in SiC devices, so the efficiency of SiC devices can reach over 90% in most applications. Initially, SiC devices were more expensive than other MOSFETs or IGBTs.
