Yaskawa inverter - the selection of high-voltage inverter precautions
First, the disadvantages
Choosing too high a voltage level results in too high an investment and a long payback period. With the increase of the voltage level, the insulation of the motor must be improved, so that the price of the motor increases. The increase of voltage level increases the number of series connections of power semiconductor devices in the inverter, and the cost rises.

Yaskawa inverter - introduction to the classification of high-voltage inverter
Current type high-voltage frequency converter
It is named because the inductive element is used in the DC link of the inverter, and its advantage is that it has the ability to operate in four quadrants, and it is easy to realize the braking function of the motor. The disadvantage is that the inverter bridge needs to be forced commutation, the device structure is complex, and the adjustment is more difficult.
