What are the differences between SiC SBD and SiC MOSFET? SiC SBD and SiC MOSFET are chips made of polarized silicon carbide material, which have high heat dissipation and conductivity. The difference lies in:

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.

Analysis of Silicon Carbide (SiC) Technology Barriers: What are the Silicon Carbide Technology Barriers Groove type silicon carbide power devices have greater manufacturing difficulty. According to the different device structures, silicon carbide power devices can be mainly divided into planar devices and trench devices. Flat silicon carbide power devices have good unit consistency, simple manufacturing process, but are prone to JFET effect and have high parasitic capacitance and on state resistance. Compared to planar devices, groove type silicon carbide power devices have lower unit consistency and more complex manufacturing processes. However, the groove structure is beneficial for increasing device unit density, reducing the occurrence of JFET effect, and solving the problem of low channel mobility. It has excellent performance such as low on resistance, low parasitic capacitance, and low switching energy consumption, and has significant cost and performance advantages. It has become the mainstream direction of silicon carbide power device development.

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.

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:

SiC MOSFET module is a power semiconductor device made of a new material, silicon carbide (SiC), which outperforms mainstream silicon (Si) IGBT and MOSFET devices in high-speed switching performance and high-temperature environments. In industrial equipment applications that require higher rated voltage and larger current capacity, SiC MOSFET modules can meet the application needs, including inverters, converters, and photovoltaic inverters for rail cars, achieving low loss and miniaturization of the system.

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.

What is MOSFET VDS ringing? 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.

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.

What are the advantages of SiC MOSFET over Si MOSFET Compared with Si MOSFETs, SiC MOSFETs have many advantages, including the following:
