Overview of IGBT Technology in Electric Vehicles

Definition and Functionality of IGBT

Electric cars are efficient because of a part called IGBT. IGBT stands for insulated gate bipolar transistor. It mixes fast switching from MOSFETs with power control from bipolar transistors. This device connects the battery to the motor and controls electricity flow. It helps the motor work well and saves energy by reducing waste.

IGBTs can handle high voltages and currents, which is great for EVs. They turn electrical signals on and off quickly. This lets the motor change speed and power based on driving needs. Smooth acceleration, braking, and energy saving depend on this feature.

Benefits of Silicon Carbide (SiC) Technology

Silicon carbide (SiC) is changing how electric cars work. SiC chips convert power faster and waste less heat than regular silicon chips. This saves energy and improves EV performance.

• SiC chips handle heat better, so cooling systems can be smaller.

• Faster switching means batteries charge quicker, which is handy for drivers.

• SiC chips waste less energy, making them eco-friendly.

• Smaller SiC parts make EV systems lighter and more efficient.

1. SiC chips carry five times more current than silicon chips.

2. They switch ten times faster, allowing smaller components.

3. They handle higher voltages, making traction inverters more compact.

SiC chips work well at high temperatures and voltages. They are smaller and lighter, which is great for modern EV designs.

Choosing Between IGBT and SiC for EV Applications

Choosing between IGBT and SiC depends on cost, efficiency, and needs. IGBT systems cost less, so they’re good for heavy-use tasks where price matters. SiC chips are more efficient, especially for lighter tasks, and they switch faster.

IGBT systems are 98.2% efficient when paired with SiC diodes. SiC MOSFETs with SiC diodes reach about 99% efficiency at full load. SiC converters stay over 90% efficient at high speeds, making them great for lightweight designs.

Note: SiC chips work better but cost more. For budget-friendly EVs, IGBT is a good choice for balancing cost and performance.
