UPS中CLA协同控制双Buck逆变器设计
Design of dual-buck inverter with CLA synchronic control in UPS

不间断电源（UPS）对逆变环节的可靠性要求高，UPS系统中DSP需承担检测、保护、通讯和变流等功能，传统单核DSP难以适用. 为此，提出一种运用内嵌控制律加速器（CLA）的DSP控制高可靠性的UPS系统设计方案. 逆变环节采用双Buck拓扑结构提高可靠性；通过对UPS主电路拓扑和双Buck逆变工作原理分析，运用DSP TMS320F28069的CLA功能分担系统任务进行协同控制，不需增加额外的DSP，实现UPS系统设计. 最后通过一台1kW的实验样机，验证设计方法的可行性.
In view of the high reliability requirement of the UPS(uninterrupted power supply) to the inverter circuit，and the conventional DSP with single core in the UPS is difficult to implement the functions of detection，protection，communication and current converter. A design scheme of UPS system with high reliability by using the DSP CLA (control law accelerator) is processed. The topology structure of dual-buck inverter is adopted to improve the reliability of the inverter；through the analysis of the UPS circuit topology and the operating principles of the dual-buck inverter，and using the TMS320F28069 DSP with the CLA sharing the functions of the UPS’s task，and can achieve the UPS system without additional DSP. Finally，the feasibility of the design method is verified a 1kW experimental prototype
