HPVFQ Four-Quadrant Inverter
HPVFQ series are Four Quadrant Frequency Inverter with vector control technique and energy regeneration
technique, having the excellent motor control performance. Adopting the double PWM control technique to increase the
power factor of system and realize the four quadrant running of the motor and meet the speed adjustment requirements of various loading,which can feed the regenerative power of the motor back to the electricity grid ,thus achieve
the purpose of maximum saving energy.
