[Abstract]:With the popularization of computer technology and the development of information network technology, the requirement of electrical equipment for power supply quality is more strict. The digital control and intelligent monitoring of UPS has become the mainstream direction of development. The development goal of UPS power supply system is to realize intelligent, green, high efficiency and energy saving and modularization. The development of information technology helps to extend the CVCF-PWM inverter power supply to the digital direction. In many UPS uninterruptible power supply, backup UPS has strong practicability and wide application. This paper introduces the design of a 3 kW backup UPS power supply based on DSP. Firstly, the first chapter of this paper introduces the current situation of UPS power supply, the future development trend and the contents of this paper. According to the requirements, the whole design scheme and the block diagram of the system are given. Secondly, the second chapter introduces the design of a practical 3kW single-phase backup UPS power supply based on DSP, including EMI filter, rectifier circuit SPWM inverter circuit, battery charge and discharge circuit design, switch tube and inverter transformer parameter calculation. The design of liquid crystal display circuit, including battery charge and discharge circuit and SPWM inverter circuit is the focus of this design. Thirdly, in the third chapter, the application method of the system software is explained in detail, the function of TMS320F2812 is introduced in detail, the flow chart of the main program and the flow chart of each subroutine are given, and the software control scheme is discussed. The control strategy of inverter is described in detail, including the software realization of SPWM wave of DSP and the software design of digital pid and its tuning method.
