| Abstract: | Based on the PWM （pulse width modulaton） AC convert technology, the chopping airfield CCR （constant current regulator） is proposed . It is made up of an AC-AC buck converter which can adjust the output voltage to get the sine wave load current with high quality and stability. The experimental results of 1kVA prototype indicates that this type CCR can always output stable sine wave load current in despite of the input vohage or the load changes suddenly. It can accord well with the CCR standard of the civil aviation. |
