摘要
传统逆变电源,由于其多采用模拟式或模数混合式控制电路,效率低、可靠性差,难以满足高端电子设备的要求。为了改善逆变电源的输出波形质量,提高其供电品质和可靠性,结合当前科研任务,通过分析空间电压矢量脉宽调制(SVPWM)的基本原理,提出用DSP生成SVPWM波的逆变电源全数字控制方法,在分析TMS320LF2407A数字信号处理器芯片特点的基础上,给出系统实现的软硬件结构、控制算法和实现结果。原理样机试验表明,该研制方案是可行和有效的。
The control circuitry of the traditional inverter power supply are almost analog circuit or analog digital circuit, its efficiency is not high and the reliability is bad, and it is hard to satisfy the request of the high level electronics equipments. To improve the output wave quality of the inverter power supply, and raise its quality and reliability, this papei＂ combines the current research task, through analyzing the basic principle of space voltage vector PWM （SVPWM）, using DSP to produce SVPWM wave to accomplish control of the inverter power supply. Based on analyzing the characteristic of TMS320LF2407A DSP chip, the soft-hardware structure, control arithmetic and experiment result of the system design are given. The sample machine proves the possibility and the usefulness of the design scheme.
