Static Electric Voltage
i-PFC (Inverter based Power Factor Correction) is trademark name for the Static Var Generators (SVG) developed and manufactured at InstaSine. Making use of advanced controllability of 3-Phase 3-Level IGBT based voltage source inverter architecture, i-PFC SVG does precise power factor and unbalance correction without the need of any passive power factor correction capacitors.
Key Benefits
- Negligible gap between the kVAh and kWh units in monthly electricity bills.
- Balanced three phase currents free from negative sequence component.
- Reduced energy losses with improved plant efficiency
- Restored ability of existing electrical infrastructure to operate at full-load capacity
- No harmonic resonances/amplifications
- Relatively maintenance free
- No AC capacitor banks, does not require contactor replacement
- No capacitor explosion risk and no accidents and/or risk of safety
- Cost-effective and highly reliable solution
