The lab studies power electronics, which converts and controls electric power into the form needed.
AboutAbout the lab
Converting electrical energy into the form needed and controlling it.
The Electromagnetic Engineering Lab studies power conversion and control technologies that are widely applied at every stage of the generation, transmission, and use of electrical energy.
Power electronics is a technology that changes voltage, current, and frequency into the form needed, based on the switching operation of power semiconductor devices.
It can not only convert but also control power at high speed and with high precision, and is regarded as a key technology for energy saving.
Its applications keep expanding, from electric vehicles, electric aircraft, electric railways, and mega solar plants to power systems.
Key terms
- Power electronics
- A technology that uses semiconductors to convert and control the form of electricity, such as voltage, current, and frequency
- Power semiconductor device
- A semiconductor element that can switch large amounts of power on and off at high speed. It is the core component of power converters
- Switching
- Turning the flow of electricity on and off in an extremely short time using semiconductors
ResearchResearch themes
The lab studies power conversion and control technologies that are widely applied in the generation, transmission, and use of electrical energy. It works on converters for mobile vehicles, electric railways, renewable energy, and power systems.
