Top Brand China Noker Ac Drives Medium Voltage 6/10kV High Efficiency Vsd

Short Description:

High voltage ac drive is high-high voltage device, which is controlled by DSP, with the SVPWM and cell in series multi-level technology to guarantee the inverter to suit industrial fields. The harmonic content is much smaller. It has high power factor and good output wave quality without input filters, power factor compensation device and output filter. Motor heating caused by harmonics and Torque ripple, noise, dv/dt, and common mode voltage problems are also avoided. It fits for asynchronous and synchronous motors.

The high voltage ac drive was awarded as national key new products in 2003, and had been widely used in motor control.

Working principle

The structure of JD-BP37/38 series high voltage inverter includes phase shifting transformer, power cells and controller.

6kV series inverter contains 5 cells each phase, 15 cells in total.
10kV series inverter contains 8 cells each phase, 24 cells in total.

The structures of power cell are common. It is the AC -DC - AC single phase inverter circuit, rectifier diodes are for the three phase full-wave, IGBT 23inverter bridge controlled by sinusoidal PWM technology. Each power cell is same, it is easy to commission, maintain and do the spare, if a failure occurs, the up bridges are on to achieve the bypass and the output of the inverter is decelerating.
