According to the chip industry market news, industrial and automotive IGBT demand remains tight, IGBT supply is in short supply, and most companies have extended and have not yet eased the delivery cycle.
Shortages of IGBTs are expected to continue until 2024. The reasons for the igbt shortage can be put down to three simple factors. First, limited capacity and slow expansion; Secondly, automobile demand is strong, silicon carbide consumption is reduced, resulting in a substantial increase in the demand for IGBT; Third, the proportion of IGBT used in the current solar inverter is greatly increased, and the green energy market drives the IGBT market.
1. IGBT has limited capacity and slow expansion
Most 6 "and 8" fabs will depreciate due to cost effectiveness, and few 6" and 8" fabs will expand IGBT capacity. But some 12-inch fabs are already producing IGBTs.
While IGBT's customer and order size is growing, it will take time to adjust capacity to downstream contract factories, which focus on consumer electronics with large and stable order sizes. The IGBT shortage is unlikely to ease in the short term.
2. Strong demand for automobiles and reduced consumption of silicon carbide led to a substantial increase in the demand for IGBT
The number of IGBTs used by electric vehicles is 7-10 times that of conventional fuel vehicles, up to hundreds of IGBTs. IGBT manufacturing cost is lower than silicon carbide, because of the simple structure, low failure rate, IGBT also has better capacitance performance and better resistance to overvoltage, suitable for high power, large current application scenarios.
3. Green energy market drives IGBT demand
According to analysts, 244GW of new photovoltaic capacity will be installed globally by 2022, while 125 million electric vehicles will be on the road by 2030, according to the International Energy Agency (IEA).
Based on the calculation that IGBTs account for 18% of the cluster inverter BOM cost and 15% of the centralized inverter BOM cost, the PV inverter IGBT market is expected to exceed 10 billion in 2025.
The IGBT market is expanding, driven by several green energy markets, but it will take some time for IGBT supply to ease due to a number of factors.
