| Abstract: | The whole digit AC servo system was based on DSP. The TMS320F240 chip was adopted by control loop and the three-phase current was detected by isolation sensor. The three-phase current could be calculated through two-phrase current, which was detected by two current sensors. The main loop includes a three-phase bridge, an inverter module with three IGBT power tubes, a braking circuit and protecting circuits, etc. The inverter module, the braking circuit and protecting circuits were integrated in high-power IPM module. |
