HEFFTRON |Active Harmonic Filter


Active Harmonic Filter (AHF) is a device to filtering harmonic current generated by non-linear load. Besides compensate harmonic current, it can also compensate reactive power and unbalance.

The AHF (Active Harmonic Filter) acquires the current signal of the load by the CT, separating the harmonic by the intelligent FFT (Fast Fourier Transform). The DSP (Digital Signal Processing) sends PWM signal to the internal IGBT. AHF will generate the compensation current with the same value but opposite phase as the system harmonic in order to achieve the real time dynamic filtering function.

HEFFTRON| Static Var Generator


Static VAR Generator (SVG) is a new technology of an instantaneous step-less reactive power compensators.

The SVG acquires the current signal of the load by the CT, the DSP tracks the command current in quick than calculate the reactive power rate of change by intelligent algorithm as to send the data to the IGBT by PWM signal. Finally the inductive or conductive power compensation current is generated on the inverter to achieve the real time dynamic reactive power compensation.
