400Hz intermediate frequency static variable power supply provides reliable support for power consumption scenarios with multiple advanced technologies and excellent performance.
Adopting unique instantaneous double-loop control, it features high control accuracy and good waveform quality, adapting to various loads; using sine wave pulse width modulation (SPWM) technology and internationally advanced IGBT/IPP power modules, it has small size, light weight, low noise, high efficiency and stable performance.
This single unit is equipped with parallel capacity expansion function, and can form a large-capacity centralized power supply system with accessories such as distribution cabinets and voltage drop compensators, which is applied in places where aircraft are parked centrally such as maintenance hangars and airport aprons.
The system connects multiple power supplies in parallel through a distribution cabinet and outputs power to multiple机位. Each channel is equipped with a voltage drop compensator to automatically compensate for the cable voltage drop. The system automatically identifies the master and slave units according to the power-on sequence of the power modules. The one powered on first is the master unit, and the one powered on later is the slave unit. The system adopts an intelligent configuration strategy, automatically starting and stopping the power supply according to the load size or the number of aircraft. When a power supply fails, it can automatically shut down and脱离 the parallel system without affecting the normal operation of other parts.
In summary, 400Hz intermediate frequency static variable power supply, program-controlled intermediate frequency power supply and intermediate frequency transformer power supply differ in output frequency, application fields and performance characteristics. When choosing, comprehensive consideration should be made according to specific needs and application scenarios.
