Aircraft Ground Power Supply (EHWA TECHNOLOGIES INFORMATION Co., Ltd.)
Aircraft Ground Power Supply
- HS Code
- Certification NEP, NET, K MARK, CE
- Patent [10-1517283]Aircraft Ground Power Supply
- Awards Acquired technology certification for Incheon Airport pilot project
- Features
Before takeoff, the aircraft stops at the apron and operates an auxiliary engine to supply power necessary for maintenance of the internal equipment. It is a stationary power supply that stops the operation of aircraft engines that cause emission of harmful substances, and instead supplies power (200VAC, 400Hz, 90kVA) necessary for maintenance of the aircraft's internal devices continuously.
This product is a power supply that receives three-phase 380V, 60Hz commercial power and converts it into three-phase 200V/115V, 400Hz AC power used in aircraft and supplies power.
It goes through the double power conversion step of the rectifier unit (AC/DC conversion unit) applied with the 12Pulse SCR phase angle control rectification method and the inverter unit (DC/AC conversion unit) to which the multilevel PWM inverter method is applied.
Develop and manufacture to supply stable power suitable for all aircraft types.
By using a high-performance/high-reliability digital controller, the power converter can be controlled in an optimal state.
