摘要:
机车变流器由于开关频率和功率损耗的原因,需合理使用PWM调制策略以满足系统在不同频率段的控制要求。在研究各种调制模式数学模型的基础上,提出了以DSP为基础的工程数字实现方法。通过仿真和试验验证,证明了该方法的正确性。
Abstract:
Due to the direct relation between switching losses and operation frequency of locomotive converter, proper modulation modes should be used to meet the requirement of different frequency sections. Based on asynchronous modulation, synchronous modulation and single pulse modulation, a project achieving method with DSP was provided. Simulation and experiments proved the validity of the method.
