The thesis is one DSP-based On-Line UPS with USB2.0 communication interface and monitor software. The system is consisting of three sub-systems. The sub-system one is the DSP development system:First step, it uses the DSP to generate the PWM signal to inverter.Second step,ultilizes the ADC module of the DSP to implement the P type current controller in the inner feedback loop and P-I type voltage controller in the outer feedback loop.Third step,accomplishes the synchronous detection via ETU. And then transfer the UPS system parameters to USB2.0 development board through EMI.The sub-system two is the USB2.0 development system and the monitor software:The function of this sub-system is to transmit the parameters from DSP to PC in the specification of USB2.0.In order to achieve the goal, the firmware is required for the USB development board.Once the monitor software is activated, the firmware is downloaded to the board.The sub-system three is the electronic devices:like inverter¡Bconverter¡Bpfc¡Bpower board¡Bbattery etc.Those devices constitute the fundamental hardware circuits modules of the UPS.
