Testing and Inspection Methods for Silicon Carbide (SiC) Diodes Silicon carbide (SiC) diodes have low switching losses, high reverse withstand voltage, and thermal stability, and have been widely used. Here are the usage and testing methods for SiC diodes:

The difference between Schottky diodes and silicon carbide Schottky diodes Schottky diodes and silicon carbide Schottky diodes are two different types of diodes.

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.

Prospect sharing of silicon carbide (SiC) substrate sheets Silicon carbide (SiC) substrate is one of the key materials for manufacturing SiC devices, which can provide high lattice matching, low defect density, and high-quality surface flatness. With the continuous expansion of the silicon carbide power device market, silicon carbide substrate sheets have also been widely used and are expected to continue to maintain rapid growth in the coming years.

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.

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.

Calculation method and formula for MOS transistor losses The losses of MOS transistors can be estimated by calculating their current losses and power losses. Current loss refers to the loss caused by the passage of current inside a MOS transistor, which is due to the resistance loss between electrons and the silicon substrate when passing through the MOS transistor. This loss can be calculated using the following formula:

The working environment and application market of SiGaNSiC MOSFETs and Si IGBTs Compared with MOSFET, SiC perfectly solves the problem of difficult simultaneous implementation of high voltage and high frequency in silicon-based materials. Based on compatibility with high voltage and medium frequency, SiC MOSFET has become the optimal solution for electric vehicles, charging stations, and photovoltaic inverters (without considering cost) due to its high efficiency and small size;

The requirements for the driver board of SiC silicon carbide MOS dual pulse testing equipment are as follows: The requirements for the driver board of SiC silicon carbide MOS dual pulse testing equipment are as follows:

Circuit symbols for silicon carbide (SIC) MOSFETs The circuit symbol of silicon carbide (SiC) MOSFET is similar to that of traditional silicon MOSFET, except that some special markings are added to the symbol to indicate its characteristics.
