In the era of pursuing efficient, lightweight, and low loss electronic design, silicon carbide (SiC) MOSFETs have become the "performance accelerator" in the fields of new energy and industry due to their high frequency efficiency, strong voltage resistance, and high reliability. This article combines real cases of new energy vehicles and photovoltaic inverters to analyze how SiC MOSFETs can help engineers overcome energy efficiency and cost challenges.

1. SiC MOSFET: Redefining the "golden triangle" of power devices. Traditional silicon-based MOSFETs face efficiency bottlenecks in high voltage and high temperature scenarios, while SiC MOSFETs break through the bottleneck with three core advantages: high frequency and high efficiency: switching frequency increased by more than three times, conduction loss reduced by 50%, significantly reducing energy waste; Voltage and heat resistance: breakdown voltage up to 3300V, working temperature exceeding 200 ℃, suitable for harsh environments; Volume reduction: Under the same power, the device volume is reduced by 60%, helping to miniaturize the equipment.  

2. Practical scenario: How SiC solves the "big concern" of engineers Scenario 1: New energy vehicles - the game between range and charging Engineer pain point: How to improve energy utilization when battery capacity is limited? Huaxuanyang Plan: HC2M008012K

Application of SiC MOSFET (1200V/80mR) in OBC and DC-DC converter design

Result: The system efficiency has been improved to 96%, energy loss has been reduced by 30%, and the battery life has increased by 8% under the same battery capacity.

Scenario 2: Photovoltaic Inverter - Power Loss in Shadow Pain Point for Engineers: Fluctuations in lighting can cause a sharp drop in efficiency of traditional devices and poor system stability. Huaxuanyang Plan: HC2M0045170D

The application of SiC MOSFET (1700V/45mR) in string inverters results in a maximum power point tracking (MPPT) efficiency of 99.5%, a 12% increase in power generation in low light environments, and a 3-year extension in lifespan.   

3. Hua Xuan Yang Electronics‘ "Precision Way": Not only does it differentiate itself from competitors in terms of parameters, but Hua Xuan Yang SiC MOSFET focuses on three major user values: reliability: passing 1000 hours of high temperature reverse bias (HTRB) testing, with a failure rate of less than 0.1%; Cost controllable: optimized substrate process, priced 15% lower than international brands; Usability: Multiple packaging options, supporting direct replacement and upgrade of SiC MOSFET in different scenarios
