APF (Active Power Filter) is a new power electronic harmonic filtering device based on voltage source inverter that dynamically generates reverse harmonic current through real-time detection of load current waveforms to achieve filtered (offset) harmonic,dynamic reactive power compensation system,voltage fluctuations,resonance suppression,power factor improvement,and other functions.
APF module generates PWM-signal of the internal IGBTsthrough DSP calculation. It has complete protection function and stable performance. Output characteristics cf the system are not affected, no danger of harmonic amplification,fast response,wide filter range,high filtering efficiency,small size and light weight.It has become an important means of harmonic suppression and reactive power compensation.
Working principles:
1. External current transformer(CT)could detect real-time load current .
2. Internal DSP calculates and analyzes the reactive power content of the system.
3. Control PWM to send signal to IGBT to generate reactive power compensation current for power factor compensation.
