| Abstract |
This paper deals with Real time integration phase locked loop (RTI- PLL) method for Inverter and Mains voltage frequency and phase matching in Uninterruptible static power supply systems. By applying this method, using a quick fault detection in the system and by an appropriate filter element selection it is possible to avoid parallel load supplying (from inverter and mains) and save middle tap choke in a static switch. In this way, a small response time of the system on disturbances and a very small increasing of the harmonic content in inverter output voltage is reached. |
