Working Principle
Advanced Real-Time Compensation
Our SVG utilizes advanced power electronics and a three-level topology to dynamically generate or absorb reactive power. By continuously detecting the load current and voltage phase, the system calculates the exact reactive current required and controls the IGBTs to output precise compensation. This ultra-fast process ensures the power factor is maintained at unity (±1) while simultaneously filtering harmonics, significantly improving the overall power quality of the grid.
Three-Phase Load Balancing
Designed for versatile application, this SVG is highly effective in both three-phase three-wire and three-phase four-wire systems. It actively balances unbalanced three-phase loads and reduces excessive neutral line currents. This makes it an ideal solution for rural power grids with severe load imbalances, as well as various complex industrial environments, ensuring safe and stable power distribution.
