power electronics in automobile


 What are Power Electronics?

Power electronics refer to the type of electrical engineering that deals with the conversion of electrical energy, through processing high voltages and currents. Examples of power electronics include: rectifiers, inverters, AC-DC and DC-DC converters, inductors and capacitors, power semiconductors and transformers. In EVs, these components are used to charge and discharge the battery, control the motor and regulate the power flow. Distrelec supports electrical engineers by providing a range of power electronics products.

Power electronics for EVs are increasingly using wide bandgap (WBG) materials like gallium nitride (GaN) and silicon carbide (SiC). In comparison to conventional silicon-based devices, these materials offer greater efficiency, higher switching frequencies, and enhanced thermal properties. Faster switching is made possible by WBG semiconductors, which results in lower power losses and more compact, smaller power electronic systems.

Importance of traffic signal rules

Image
    Adhering to traffic rules and traffic signals is crucial for maintaining road safety and preventing accidents. These road rules and signs are the foundations for smooth movement of vehicles and an efficient network of roads.    Accident prevention:  By following the road safety rules, road users can avoid collisions and injuries. Traffic signals play a crucial role in preventing accidents by regulating the flow of vehicles and ensuring that drivers and pedestrians regulate their movement on the road.  Traffic congestion mitigation:  Well-timed and efficient traffic signals help to reduce traffic congestion by coordinating the movement of vehicles and preventing bottlenecks. This improves traffic flow, reduces travel times, and saves fuel. Pedestrian safety:  Traffic signs and signals provide clear instructions and warnings to pedestrians, allowing them to safely cross the road at designated times. This reduces the risk of pedestrian accidents....

Artificial Intelligence for Road Safety

Image
  Telematics for fleets and insurance started with essential questions concerning: geolocation of vehicles fuel level monitoring the number of kilometers on the dashboard These solutions are now fully operational. We then saw applications while driving: eco-driving tips to save fuel navigation, to save travel time or km Again, these elements are currently being deployed. Similarly, eco-driving assistance applications are being deployed to try to reduce the cost of energy-related operations. But the artificial intelligence that can be embedded in telematics systems (device, smartphone) can provide many other services. In particular, it is possible to significantly reduce the number of road accidents, thereby reducing operating costs. COST OF ROAD ACCIDENTS Road accidents cost fleets dearly: repair costs, if the fleet is self-insured, insurance costs otherwise cost of the immobilization period of the damaged vehicle cost of non-working time of injured personnel cost of late delivery ...

Biodiesel vs. Diesel Fuel

Image
  There are significant differences in environmental impact when comparing biodiesel and diesel’s life cycle emissions. While both fuels produce similar amounts of carbon dioxide during combustion, biodiesel’s carbon dioxide emission is partially offset by the growth of plants like soybeans and other feedstock used to make biodiesel fuel. This leads to a notable decrease in net carbon dioxide emissions over its life cycle. The U.S. Department of Energy reports that pure biodiesel emissions are  reduced by 74% compared to diesel . Meanwhile, a B20 blend  reduces carbon dioxide emissions by 15% . The difference between diesel and biodiesel is also apparent when observing other emission pollutants. Research  published by the Institute of Physics  (IOP) revealed the following results: Carbon monoxide:  Pure biodiesel produces significantly lower carbon monoxide emissions than regular diesel. Hydrocarbon:  Diesel generates higher hydrocarbon emissions ...
