Comparison of PIM modules with separate inverter and rectifier schemes in inverter applications

Abstract:
As we all know, in many industrial fields, such as frequency inverters, servo motors need to use rectifiers and inverters. Their circuit topology diagram is the rectifier bridge plus three-phase inverter circuit. Here we take the frequency converter as an example. Generally speaking, the motor power range of the low-power inverter is 0.4-3KW, the motor power range of the medium-power inverter is 3-30KW, and the motor power range of the high-power inverter is 30-200KW. In the low power segment of the inverter, there are single tube and module schemes to choose, this paper is mainly introduced in the module scheme integrated PIM module and rectifier bridge and inverter separate two different scheme choices.
