Power Quality Solutions

Delta PQC series power quality solution consists of the Active Power Filter (APF) and Static VAR Generator (SVG). Both provide an active compensation solution based on power electronics technology.

Compared with conventional passive compensation solutions such as capacitor banks, an active compensation solution improves the reliability and quality of the power distribution system.

Special Features of Delta Power Quality Solution:

High Adaptability

Wider range of operating temperatures
Delta PQC series APF & SVG can normally work from -10~55°C, which is suitable for most applications
Withstands extreme electrical condition
Delta’s PQC series APF & SVG can withstand severe harmonic distortion of voltage, they can work normally under conditions with THDu (total harmonic distortion of voltage) up to 15%
Compatible with diesel generators

Simple and Flexible Application

The Delta PQC series APF & SVG’s modular structure makes it easy for installation, maintenance and capacity expansion.
APF & SVG modules can be embedded in Delta’s standard cabinets or third-party cabinets, making it possible to customize cabinets for special requirements.

Excellent Compensation Capability

Delta’s PQC series APF & SVG adopts 3-level inverter topology with 3pcs modular IGBT and up to 30 kHz switching frequency, which provide excellent power quality compensation accuracy, response speed and output ability.

High Reliability

Module redundancy technology
Intelligent air cooling technology
Top brand electronic components
Advanced production technology

Active Power Filter (APF)

Delta PQC Series is an advanced modular active power filter (APF) system. Our highly reliable power quality products are based on the global R&D and large-scale production of Delta Group. The PQC Series is widely used in process industries...

Static Var Generator (SVG)

The principle of the SVG is very similar to that of Active Power Filter, as demonstrated in the picture below. When the load is generating inductive or capacitive current, it makes load current lagging or leading the voltage. SVG detects the phase...
