Power semiconductors, a vital component of semiconductors and essential for power processing, are used for voltage/frequency conversion and DC-AC transitions. The global market value grew from $38.1 billion in 2019 to $42.6 billion in 2022, with a CAGR of 5.43%. As a major subset, power semiconductors are widely applied across power electronics sectors, with automotive, industrial, and consumer electronics as the top three end - markets.
With the rise of new energy vehicles, both in - vehicle applications and charging piles are important incremental markets for MOSFETs. MOSFETs are core components in automotive electronics. Automotive engines, transmission controllers in the drive system, as well as braking, steering control, vehicle body lighting, and intelligent mobility all rely on MOSFETs.
MOSFETs are widely used in automotive components such as (brushed and brushless) DC motors and power supplies. As the application scenarios of automotive intelligence and electrification continue to expand:
1. Intelligent applications
ADAS: Safety management, domain control systems, parking systems
Body electronics: Vehicle body power supply, central control system, temperature control, gateway system, intelligent door locks, lighting system
Chassis and safety: Suspension system, electronic power - assisted steering system, airbags, parking and anti - lock braking systems
Infotainment system: Display control, audio, instrument panel, entertainment functions, telematics
2. Electrification applications
Traditional fuel - powered vehicles: Engine and transmission management, internal combustion engine auxiliary systems, start - stop systems
New energy vehicles: DC - DC power supplies, on - board chargers
