High-Frequency Power Electronics

Most of the applications around us are powered by electricity as an energy source. Electricity is widely used in modern society because it can be easily transformed in terms of amount and form, and is well-suited for transmission. So, how exactly do we change the amount and form of electricity? The practical field that deals with the technology of electrical power conversion is called power electronics.

Power electronics has grown and evolved following the development of power semiconductor devices. These devices are one of the key components used in power converters, and their performance significantly affects the overall performance of the converter. Therefore, new power electronics technologies have been developed in response to the emergence of new power semiconductor devices. In recent years, high-performance power semiconductors such as Silicon Carbide (SiC) and Gallium Nitride (GaN) have gained attention. These semiconductors allow operation at higher power levels and higher frequencies than conventional devices.

My research focuses on high-frequency power electronics using power semiconductor devices such as SiC and GaN. By increasing the operating frequency of power converters, passive components such as capacitors and inductors can be made smaller and lighter. This enables the development of compact and lightweight power converters that were previously unattainable.
