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;

Combination of Silicon Carbide (SiC) Power Management Solutions Silicon carbide solutions support the replacement of aircraft's pneumatic and hydraulic systems with smaller, lighter, and more efficient electrical solutions to power onboard AC generators, actuators, and auxiliary power units (APU). This type of solution can also reduce the maintenance requirements of these systems. However, the most significant contribution of SiC technology lies in its mission to electrify commercial transport vehicles, which are one of the world's largest sources of GHG emissions. With the advent of 1700V metal oxide semiconductor field-effect transistors (MOSFETs) and configurable digital gate drive technology, today's SiC solutions enable designers to generate maximum productivity with minimal energy consumption for these systems.

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.

Silicon carbide diodes: an important role in the photovoltaic industry Silicon carbide (SiC) diodes have high stability and efficiency, making them suitable for various photovoltaic applications such as solar panels and solar systems. For example, in solar panels, silicon carbide diodes can prevent excessive current or overvoltage, thereby protecting solar cell components. In solar energy systems, it can also limit the charging current and control the charging and discharging process of the battery.

Introduction to Low Sensitivity SiC Power Modules Low inductance SiC power module refers to a power module that uses silicon carbide (SiC) as a semiconductor material and has a lower inductance value. Compared with traditional silicon (Si) power modules, low inductance SiC power modules have higher switching speed and lower switching losses, thereby improving the efficiency and reliability of the system.

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.

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.

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:

Application of Silicon Carbide (SiC) Ceramics in Semiconductors Silicon carbide (SiC) ceramics are a semiconductor material widely used in many semiconductor applications. Here are some typical applications of silicon carbide ceramic semiconductors:
