TAIPEI (Taiwan News) – The growth of electric cars is predicted to drive the output value of Insulated Gate Bipolar Transistors (IGBTs) to US$5.2 billion in 2021, according to a Topology Research Institute research report.
The IGBT is a power switching transistor for use in power supply and motor control circuits. As IGBTs are important components in electric cars, the demand for these parts to make electric cars can be five to 10 times more than counterparts for internal combustion vehicles, the institute said.
The number of electric cars globally is estimated to break the 8 million mark in 2021, twice as many as 2018, the report said. According to the research institute’s statistics, the annual growth rates for electronic cars in 2016, 2017, and 2018 were, respectively, 28 percent, 29 percent, and 27 percent. This compares to single-digit annual growth rates in 2015 and in previous years.
In 2018, IGBTs’ global output value was about US$4.7 billion, with an annual growth rate of 16 percent, the research institute said.
However, factors such as US-China trade talks in stalemate, the U.S. threatening to impose heavy tariffs on Mexico over illegal immigrants, and the unstable Middle East situation, could impact sales of electric cars in the second half of 2019 and drag down IGBT output. The research institute predicted that IGBT output value will reach US$4.84 billion in 2019, representing growth of only 3 percent from the previous year.
