摘要
提出了一种基于DSP的消除SPWM全桥逆变器直流偏磁问题的控制方案,采用TI公司的DSP芯片TMS320F240来实现。在一台400 Hz 6 kW样机上进行了实验,实验结果表明该方案能较好地解决全桥逆变器中的直流偏磁问题。
The DSP-based flux imbalance control of a SPWM full-bridge inverter is proposed. The control scheme is implemented using a TI TMS320F240 DSP. A 400 Hz 6 kW prototype is constructed. The experimental results prove that the proposed control scheme is able to avoid flux imbalance effectively.
