QD-MF series of high-voltage inverter Product details:? Features flexible loop control sensorless vector control to achieve a stable speed control. The need for precise speed control or high starting torque cpu IPC, the choice of speed sensor closed-loop vector control. ? High-load input power transformer secondary winding multiplex, reduce the harmonic current of the power supply pollution, meet the most stringent IEEE 519 standard. No need to install power factor compensation device and harmonic suppression device is the "Perfect Harmony drive" in the true sense. ? Quality drive motors multi-level PWM control mode, providing sinusoidal current output. Common mode voltage and dV / dt small abb industrial, motors, cables, no special requirements, frequency transformation of the old equipment, no need to replace the motor. ? Higher harmonic components of the ideal mechanical power output current contains extremely small, pulsating torque shaft system resulting impact is negligible. ? High efficiency substantially sinusoidal output current, reducing the motor harmonic losses. Input transformer primary winding harmonic small, the system efficiency of more than 97%. Without additional set output transformer, eliminating the losses resulting. Multi-level PWM control, cut its high frequency IGBT switching losses. ? High power use diode full bridge rectifier without power factor compensation, can reach more than 95%. ? High reliability IGBT inverter: The 1700V high voltage IGBT, in reducing the number of components while increasing the reliability of the system. Immunity: the use of optical fiber isolation between the control system and power unit, safe and reliable. Strong self diagnostic capabilities: timely manner to all types of emergencies the system to make an accurate early warning protection.
