POWER QUALITY MODULE SERIES

The HYAPF/HYSVG active power filter and static var generator use an external current transformer (CT) to continuously monitor the load current. An internal DSP processes this data, isolates the harmonic and reactive components of the load current, and then generates PWM signals to drive the internal IGBTs. These signals enable the inverter to produce a current that is equal in magnitude but opposite in phase to the load's harmonic or reactive currents, thereby injecting it into the grid to compensate for harmonic and reactive power, thus achieving filtering and compensation.

POWER QUALITY MODULE SERIES

The HYAPF active filter uses an external current transformer (CT) to detect the load current in real time, and employs an internal DSP to compute and extract the harmonic components of the load current. It then generates a PWM signal to drive the internal IGBTs, enabling the inverter to produce a current that is equal in magnitude but opposite in phase to the load's harmonic currents, thereby injecting this compensating current into the grid to mitigate harmonic distortion and achieve filtering.
