Japan's New Energy Industry Technology Development Organization (NEDO) has announced that the next-generation power inverter research and development organization, which is jointly established by industry, government and academia, has successfully developed the world's smallest inverter. Compared to a general inverter, it is only about one-fifth of a size and is reduced to about 500 cubic centimeters. This achievement is expected to be applied to electric vehicles and railways in the future. The inverter is a device that converts DC power into AC power. Because it can improve the rotational efficiency of the motor, it is often used in home appliances and other fields. Inverter is also indispensable in the process of connecting DC power generated by solar power into AC power transmission lines. s installation. The inverter developed this time uses silicon carbide as a semiconductor component material instead of the conventional silicon. The power conversion efficiency is improved, thereby achieving miniaturization. In the experiment, the inverter successfully drives a motor with an output power of 15 kW, which is equivalent to more than 15 times that of a household air conditioner.
