Industrial Variable frequency｜Inverter Case
As core speed regulation devices in industry, inverters are widely deployed for motor driven scenarios such as fans, water pumps, compressors and conveyor belts. High frequency on off operation of internal power devices of inverters generates massive harmonics, inrush currents and high frequency voltage spikes. These not only pollute upstream power grids but also damage downstream motor insulation and readily cause false action of peripheral instruments and sensors. As key components for power quality governance of variable frequency systems, transformers and reactors supporting inverters perform functions of voltage conversion, galvanic isolation, surge inrush current suppression, harmonic filtering and high frequency voltage spike mitigation. Custom developed for non linear load characteristics of variable frequency systems, our products feature superior harmonic suppression capacity, inrush current endurance, low loss and PWM pulse condition adaptable performance compared with general purpose industrial components. They resolve industry specific pain points including excessive harmonics of variable frequency systems, high equipment burn out risks and over voltage risks upon long cable transmission and guarantee long term stable operation of complete variable frequency drive systems.
