February 2020 – Semiconductors driving the electric vehicle industry

Published on: 12/02/2020

Power semiconductors are leading the way for electric vehicles

Semiconductors driving the electric vehicle industry by GD Rectifiers

Semiconductors driving the electric vehicle industry

With more than 227,000 electric cars (EVs) on the road today and 8,500 electric vans across 130 models and 25,733 charging points in the UK, the demand for power semiconductor components has increased tenfold over the past five years.

The surge in demand for semiconductors has stemmed from innovations in the industry providing longer electric vehicle battery life. This not only improves the logistical appeal of electric vehicles but it also provides a prime opportunity for semiconductor manufacturers and distributors.

Today’s semiconductors are driving the next generation of electric vehicles. Semiconductors are used in a wide variety of functions suited to electric vehicles, including: touch-screen interactivity with the driver and passengers and power electric batteries and components in the power train. The more digitally advanced EV, the more semiconductors it will require. As features like autonomous driving and blind-spot detection become more widespread, the automotive market will need access to more semiconductors, putting more demand on the component market.

The average amount of semiconductor components used in EVs are rapidly growing, putting a strain on the industry and it’s supply chain.

Car manufacturers are devoting their time to automotive innovations and are focusing strongly on EVs and setting aggressive sales targets, for example BMW wants EVs to be 15-25% of sales by 2025, Honda are aiming for two-thirds of its sales by 2030 and Ford plan to debut 13 new EV models by 2020.

Engineers are tapping in to the developments emerging from the expansion of EVs, especially in technology, such as 5G networks – a key development for electric vehicles as they require in-depth connectivity for vehicle system updates, emergency services communication and navigation assistance which will add to the demand for power semiconductors.


GD Rectifiers stocks a wide range of power semiconductors used in the automotive industry, designed and manufactured specifically for electric vehicles, including SiC power MOSFETs,

IGBT modules, rectifiers, circuit protection devices and voltage regulators.



Converters usually contain Inverters with Power MOSFETs or IGBTs to drive the electric motor. GD Rectifiers offers a broad range of power MOSFETs suitable for the automotive industry by IXYS and Semikron.

IXYS offers an extensive range of half bridge modules available in ISOPLUS i4-PACTM packaging. These devices are ideal for applications utilising power semiconductor devices that require heatsink grounding methods and provide unsurpassed thermal performance and temperature cycling capabilities.

Semikron offers a SEMITOP E1 IGBT module package suitable to EVs, providing maximum reliability.

Insulated-gate bipolar transistors (IGBTs)

IGBT modules play an integral role in the development of EVs and comprise of the largest segment of the semiconductor market for EV power systems. IGBTs are a high-voltage, high-current switch connected directly to the traction motor in an electric or hybrid electric vehicle. It works by taking the direct current energy from the car’s battery (through the inverter) and converts alternating current control signals into the high-current and high-voltage energy required to turn the motor. Ideal for EVs because of their high efficiency and fast switching, reducing power loss to wasted heat which results in a better mileage per watt of energy.

IXYS offers a wide range of XPT (extreme-light punch-through) IGBTs designed for electric vehicles, including: 600V XPT Planar (33A-550A), 650V XPT Planar (15A-200A), 650V XPT Trench (65A-480A), 900V XPT Planar (20A-310A) and 1200V XPT Planar (21A-240A).

Semikron’s latest generation 7 IGBTs are designed specifically for motor drive applications. They provide major reductions in forward voltage drop and allow for smaller chip sizes and increases power density by up to 45% due to the nominal current ratings in the same module package.

Dynex has developed a number of technologies specifically for EV applications, including double sided cooled IGBT modules with wire-bondless design and active gate driver technologies.

Dynex also offers a wide range of SiC diodes and MOSFETs, IGBT gate drivers and custom electric vehicles systems.
