- CTs’ reversal auto correction can be setted on HMI, support grid side or load side current detection
APF Principle
Delta’s PQC Series APF is connected in parallel with non-linear loads, and uses one set of current transformers (CT) to detect the load current. It calculates each order harmonic current by FFT algorithms in its DSP microchips, and then generates a compensating current with the same amplitude but opposite phase angles to the detected harmonic current, which cancels out the original load harmonics.
The PQC series APF not only eliminates harmonic current from the load side, but it also mitigates harmonic voltage caused by harmonic currents. The APF system can also improve power factor (PF) and correct load imbalances in the power system.
AHF Structure
Delta PQC Series APF has a modular design, which adopted 3-level inverter topology with 3 pcs modular IGBT and DC capacitor components, and the Delta Active Power Filter system consists of one or several APF modules and a 7” or 10” HMI display.
Each APF module is an independent harmonic filtering system, and users can change the harmonic filtering system rating by adding or removing APF modules.
According to the mounting type, Delta PQC series APF can be divided into Modular APF (rack mounting) and wallmounted APF.
APF Module and Cabinet Solutions
According to cable terminal type, a modular APF can be divided into two types:.
Drawer type modular APF (adding pluggable accessories on power cable terminals) Mixed fixed type modular APF (Power cables are fixed from rear side, Signal cables are fixed from front side) HMI has two types:
7’’ HMI
10’’ HMI
APF modules and HMI panel can be embedded in Delta’s standard APF cabinet or a customized cabinet. There are breakers, cable terminals and Surge Protection Device (SPD) in the APF cabinet. Delta can supply IP30, IP42, IP54 or customized solutions.
Wall-mounted APF Solutions
Delta’s Wall-mounted APF can be installed on a wall, which is suitable for low rating applications, and wall-mounted type HMI can be installed on the wall-mounted APF module, along with a mounting bracket to provide support and protection. Delta can supply IP30, IP42, IP54 or customized solutions.
