SIC MOSFET for the Next Generation of Electric Vehicles


 The global EV sector is growing by the day. But with growth come evolving consumer demands and the need to handle the dynamicity of the market. Globally, EV makers are adopting 800-V drive systems to increase vehicle efficiency, ensure rapid charging and augment the distance range of vehicles.

SiC MOSFETs are precisely helping EV makers around the globe graduate to these next-gen objectives and in power devices for EV powertrains. They have become a crucial element of EVs. Their use extends to various areas like onboard chargers, traction inverters, etc. Let’s delve a bit more into the advantages of SiC MOSFETs, especially given next-gen demands.


SiC MOSFET Advantages Over Conventional Silicon Devices and Silicon IGBTs:


Silicon devices might have ruled the EV horizon for quite some time. But SiC MOSFETs are slated to dethrone them. Of course, the reasons are valid. 

Some areas wherein SiC MOSFETs have the upper hand include voltage, frequency, and switching capabilities. Let’s look at each to understand why you must switch to SiC MOSFET to keep up with the evolving market needs.

  • SiC MOSFETs have a crucial breakdown strength, approximately ten times that of conventional silicon.
  • They can operate at high temperatures and provide a higher current density.
  • Additionally, SiC MOSFETs offer reduced switching losses and can support higher frequencies. It also refers to the fact that SiC MOSFETs are similar to silicon IGBTs and can work as a replacement for the latter to offer even more advantages.
  • They offer excellent thermal conductivity and lower switching losses. The latter refers to lesser heat generation, thus reducing the thermal management needs of the vehicle.

Other benefits include reduced operational costs, compact size, and substantially reduced weight. What’s even more significant and beneficial, particularly for EV makers, is that SiC MOSFETs are more rugged than silicon IGBTs. Hence, they are apt for harsh environment applications like onboard chargers in EVs.

But that’s not it. The benefits of SiC MOSFETs are linked to some practically measurable results that include the following.

  • The use of SiC MOSFETs can help increase the driving range of an average EV by around 500 kilometers.
  • They can help the EV pull higher energy (almost double) from an EV station.
  • Their lightweight and compact design helps reduce the weight the EV bears by around 150 to 180 kilograms.
  • SiC MOSFETs exert a lower amount of pressure on the battery. That helps increase the battery’s lifespan substantially.

Features of Tyre Pressure Monitoring System | Millennium Semiconductors

Image
  Human safety being of utmost importance on the roads, the Government keeps updating policies and standards for manufacturing of automobiles. One such for India is a new AIS 154 standard regarding technical requirements for Tyre Pressure Monitoring Systems (TPMS). To start with, A tire-pressure monitoring system (TPMS) is basically an electronic system which is designed to monitor the air pressure inside the pneumatic tires. The purpose of the tire pressure monitoring system (TPMS) in your vehicle is to warn you that at least one or more tires are significantly under-inflated, possibly creating unsafe driving conditions. The TPMS low tire pressure indicator is a yellow symbol that illuminates on the dashboard instrument panel in the shape of a tire cross-section (that resembles a horseshoe) with an exclamation point. The goal of a TPMS is avoiding traffic accidents, poor fuel economy, and increased tire wear due to under-inflated tires through early recognition of a hazardous state of

How to Choose the Right Reed Switch for Your Application?

Image
  While picking the right reed switch, you must evaluate it across a few essential aspects, including its pole and throw switch configurations, physical size, electrical specifications, etc. Let's delve into each to know how to pick the best reed switch. 1. Pole and Throw Configurations Littelfuse reed switches are available in four configurations, including, • Single pole single throw (SPST): It builds or breaks the connection of a single conductor in a single branch circuit. It has two terminals and is called a "Single-Pole" Switch. • Single pole double throw (SPDT): It builds or breaks the connection of a single conductor with any one of the two other single conductors. It has three terminals and is termed a "Three-Way" Switch. • Double pole single throw (DPST): It builds or breaks the connection of two circuit conductors in one branch circuit. Usually, it has four terminals.   • Double pole double throw (DPDT): This six-terminal switch builds o
