中文摘要:
      针对传统变频技术的不足,提出一种两相连续型阻塞式交交变频电源,具有传统变频技术所不具备的:谐波含量少、功率因数高、功率器件少、控制简单、成本低廉等优势。依据阻塞控制策略对输入两相电网电压进行阻塞拼接变换,实现调频的目的,同时采用SPWM斩波调压技术对阻塞后电压进行斩波处理,进一步实现调压的目的。使用DS1104实时控制系统完成对控制策略验证,并依靠TMS320F2812实现控制策略的实施。进一步设计主功率电路及信号调理电路,完成变频电源的相关实验,获得了典型的实验结果。实验结果与理论分析相一致,验证了提出的两相连续型阻塞式变频电源的正确性与可行性,同时也为面向家用电器、工厂中小容量排风设备的节能及换流方式的改进提供理论依据和实验指导。
英文摘要:
      Aiming at the shortage of traditional frequency conversion technology, a two-phase continuous blocking alternating current conversion power supply is proposed. It has the advantages of low harmonic content, high power factor, low power device, simple control and low cost. According to the blocking control strategy, the input two-phase network voltage is blocked and spliced to realize the target of frequency adjustment. Meanwhile, SPWM chopper modulation technique is used to cut the voltage and realize the purpose of voltage adjustment. The control strategy was verified in DS1104 real-time control system and was realized in TMS320F2812. The main power circuit and signal conditioning circuit are further designed, and the relevant experiments were completed and typical experimental results were obtained. The experimental results are consistent with the theoretical analysis and verify the correctness and feasibility of the continuous frequency conversion power supply. At the same time, it provides theoretical basis and experimental guidance for the improvement of small and medium capacity exhaust equipment for household appliances and factories.
