YTPQC-SVG Static Var Generator detects load current in real time through internal and external CT and analyzes the reactive current of load by TI DSP and FPGA, then generates PWM signal to IGBT inverter(3 Level) to generate inductive or capacitive current and compensate reactive current to realize the target power factor. YTPQC SVG can also compensate phase imbalance.
Compared with the traditional capacitor bank, YTPQC-SVG has the advantages of fast response and high compensation accuracy without under-compensation or over-compensation problems, avoid resonance,etc.
When the load is generating inductive or capacitive current, it makes load current lagging or leading the voltage. SVG detects the phase angle difference and generates leading or lagging current into the grid, making the phase angle of current almost the same as that of voltage on the transformer side, which means fundamental power factor is unit.
