1、 Introduction
Aviation static converter is a 400Hz or 50Hz single-phase and three-phase static inverter power supply specially designed and manufactured for aviation and military electronic equipment. Its output power is from single-phase 50VA to three-phase 45kVA. It can be widely used in aircraft airborne equipment, radar, navigation and other task systems as well as other places where 400Hz intermediate frequency power supply or 50Hz airborne power supply is required.
2、 Applicable places
Military aviation, navigation system switching power supply, land, sea and air detection system, satellite navigation system.

1. The inverter has good output performance and system stability by adopting high frequency switch transformation and waveform closed-loop control technology;
2. Three independent converters are used for phase-locked control, which has strong anti load imbalance ability and can be applied to three-phase completely unbalanced load;
3. The output over-current protection adopts cut-off protection, which has strong adaptability to the impact of load;
4. Using the advantages of low loss under the high frequency switching mode of MOSFET and IGBT, the SPWM converter has the characteristics of small volume, light weight, high efficiency and high reliability;
5. The standardized design makes the maintenance of converter easy and fast.
