HVVF Air Cooling Medium Voltage Drives

NC HVVF Air Cooling Medium Voltage Drives is a voltage source inverter based on IGBT and cell series multilevel PWM technology.
Characterized by low harmonics and high efficiency.
Achieve output voltage of up to 18kV with perfect sinusoidal waveform, directly driving almost all kinds of MV motors without a step-up transformer.
