Abstract:
The switched reluctance machine (SRM) stands out as a preferred choice for electric vehicles due to its numerous benefits, such as its uncomplicated design that doesn't necessitate winding installation on the rotor and operates without the need for permanent magnets. SRM has the ability to run at high RPM. SRM with 3-phase asymmetric converter can be used as a generator, called Switched Reluctance Generator. The generation process of SRM involves employing negative torque. SRM performance tends to be highly inefficient under low-speed conditions, primarily because the negative torque magnitude becomes minimal. Two operational methods for SRM, stemming from the DSPIC30F4012, are single-pulse control and PWM control. A rotary encoder is required in addition to the converter to detect the rotor position and obtain a serial pulse. This paper will propose a generating approach employing a magnetizing-demagnetizing control strategy, which serves as an illustrative instance of PWM control techniques.
