- Abstract:
-
A single-phase voltage type active filtering device (APF) based on DSP technology is introduced, and the main circuit structure, the calculation method of reactive and harmonic current to be compensated and the capacitor voltage stability control method of the device are expounded. The characteristics of DSP chip, the hardware structure of the device and the control strategy of the active filter device are analyzed, and the test results of the device show that the control strategy is feasible. The active filter device can be used for reactive power dynamic compensation of electrified railways, and can also be used for split-phase reactive power compensation and harmonic suppression of three-phase four-wire power grid.
