The power semiconductor is a type of semiconductor that can handle high voltages and large currents, and has a structure that is different from that of ordinary semiconductors. It is mainly used for voltage conversion, frequency conversion, and power conversion between direct current (DC) and alternating current (AC), and is required for inverters, converter circuits, motor control, etc. Its main demand sectors include the information and communication sectors such as data centers, consumer sectors such as home appliances, industrial sec- tors such as industrial equipment and trains, and the automobile sector.
