Product Recommendation Maker Dynamics Applications

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.

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.

The main six stages of SiC chip manufacturing The main six specific processes of SiC chip manufacturing are pre-processing, wafer processing, crystal growth, integrated circuit design and fabrication, chip testing, and integration.

What are the solutions to reduce losses in SiC modules? The SiC module loss reduction scheme mainly considers the following four aspects: adopting low voltage and low frequency design, optimizing the driver program, optimizing the structural design, and adopting low side resonance technology.

What are the measures for surge suppression? The reasons for generating surges are multifaceted, and surges are a type of spike pulse with high rising speed and short duration. Overvoltage in the power grid, switch ignition, reverse voltage, static electricity, and motor/power supply noise are all factors that cause surges. And surge protectors provide a simple, economical, and reliable protection method for power surge protection of electronic devices.

SiC MOS driver design SiC MOS driver design is a complex process that requires consideration of many factors, such as electrical performance, thermal characteristics, and packaging selection. To improve reliability and performance, the following aspects should be considered:

Comparison of driving circuit differences between SiC MOSFET and Si IGBT SiC MOSFET and Si IGBT are both indispensable products for the development of electronic products. SiC MOSFET and Si IGBT have many common characteristics and differences. Therefore, the following is a comparison of their product differences:

Silicon carbide (SiC) diodes are diodes made from silicon carbide as raw material. Silicon carbide diode, claimed to have zero reverse recovery time, is a dedicated boost diode for high-efficiency PFC boost circuits.

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:

What is SiC MOSFET? SIC MOSFET (Silicon Carbide MOSFET) is a new type of semiconductor device with high thermal stability, high conductivity, and high frequency characteristics. Learning SIC MOSFET includes the following aspects:
