Electrical drive systems play a key role in energy savings. They account for two-thirds of electrical energy consumed in industry and they are a central component of automation systems. There are two distinct industrial drive technology groups. The first group includes electrically driven machines requiring position control. This group includes, for example, machine tools, measuring machines and packaging machines where precision in movement is required. The second group covers all applications where a fluid is moved by pumps and fans. Here variable speed drives allow the flow to be aligned with the needs of the process. Compared with traditional methods of flow control like throttling and bypassing, electronic speed control significantly increases overall efficiency. Furthermore, an inverter enables more efficient motor technologies, like permanent magnet synchronous motors and reluctance motors, to be used. Today, these drives can be implemented in a power range from watts up to megawatts.

 

 

 

Nearly all static converters for electrical drives used today employ a combination of input rectifier, DC link and output inverter. If no regeneration system is required for the electrical drive, the most competitive semiconductor components for the input rectifier are bipolar thyristors and/or diodes offered in various topologies, such as complete 6-pack modules, half-bridge modules or single modules. In high-power electrical drives, the input rectifier consists of thyristors and/or diodes in Presspack housings. If regeneration is required, an active front end can be designed using IGBT modules. In the low-power range, where power factor correction is mandatory in some applications, PFC (power factor correction) circuits can be designed using discrete IGBTs and diodes or dedicated modules.
