• 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.

• Design and Manufacturing Process of Silicon Carbide (SiC) MOSFET Chip For silicon carbide MOSFETs (SiC MOSFETs), high-quality substrates can be purchased externally, and high-quality epitaxial wafers can also be purchased externally. However, this only provides a good foundation for obtaining a silicon carbide device. High performance silicon carbide devices have extremely high requirements for device design and manufacturing processes. This article will introduce you to the design and manufacturing process of SiC MOSFET devices.

• 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:

• Wide application of silicon carbide (SiC) MOSFET in new energy charging piles Silicon carbide power devices cover series such as 650V/2A-100A, 1200V/2A-90A, 1700V/5A-80A, etc. The products have been put into mass production and can fully benchmark the advanced quality and level of international brand peers. We have successively launched full current voltage level silicon carbide Schottky diodes and silicon carbide MOSFET series products that have passed industrial and automotive reliability tests, with performance reaching the international advanced level. They are applied in fields such as solar inverters, new energy electric vehicles and charging piles, smart grids, high-frequency welding, rail transportation, industrial control special power supplies, and national defense and military industries.

• Can digital signals pass through isolation chips Can digital signals pass through isolation chips? The answer is yes. Digital signals can be transmitted through isolation chips. Isolation chips are mainly used to isolate signals for the purpose of electrical isolation, ground isolation, or optical isolation. Isolation chips typically consist of two parts: isolation front-end and isolation back-end.

• What are the design issues of inverters during the transition from silicon to silicon carbide (SiC)? The design of silicon carbide device inverters is a complex process that requires consideration of many factors to ensure their reliability and performance. Therefore, designers need to fully understand the characteristics of silicon carbide devices and make corresponding adjustments during design to ensure that the inverter can meet the requirements of the application environment

• Calculation methods for P-channel enhanced VDS and CGS In a P-channel Enhanced Mode FET, VDS represents the voltage between the drain and source, while CGS represents the capacitance between the gate and source. When calculating VDS, it is necessary to consider the working state of the P-Channel Enhanced Mode FET. Generally, the following formula can be used for calculation:

• 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:

• 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.

• 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.
