Design of Switched Reluctance Motor Controller Based on STM32

Using the STM32F103RBT6 as a main control chip based on the ARM kernel,a controller is designed in combination with three-phase low cost,high performance switched reluctance motor.The main circuit is composed of the IGBT asymmetric half bridge circuit,driven directly by the low-cost isolation chip PC923,with protection of the over-current,over-voltage and undervoltage.Using the CCC control means in low speed and APC control means in high speed,the system is reliable and has good performance.The system hardware and software design are introduced in detail and the experimental results are given finally.
