1. 400V Static Var Generator Overview
Enjoypowers’ 400V Static Var Generator SVG module is a three-level inverter reactive power management system used for power factor correction, power harmonics filtering, three-phase load balancing, effectively reducing line loss, and prolonging the service life of power equipment.
Enjoypowers’ 400V Static Var Generator SVG’s modular design allows flexibility in installation and integration. It is a preferred power quality solution for all power consumers, system integrators, and OEMs.
2. Static Var Generator Operating principle
Enjoypowers’ SVG is a device based on power electronics technology, which is connected in parallel with loads requiring harmonic mitigation. SVG works as a controlled current source and provides any type of current waveform in real-time.
When the load generates inductive or capacitive current, it makes load current lag or leads to the voltage. SVG detects the phase angle difference and injects leading or lagging current into the power system in real-time, so that the phase angle of current is almost the same as that of voltage, so as to unify the basic power factor.
