Research and Development for DSP-based ON-Line Uninterruptible Power Supply with Parallel Operation

The thesis is accomplished two DSP-based On-Line UPS using voltage and current control to implement the parallel operation. Each inverter in the parallel operation system has the same control method. The system can reduce the zero crossover distribution causing by SPWM and the influence causing by load variation with inner current and outer voltage loop control which are taking advantage of P and PI control respectively. On the premise of the same system parameters, the two system can achieve the synchronous between phase and frequency by the control of digital PLL circuit to eliminate the circulation current.
