| Abstract |
Control strategy for reducing inrush current when a load of capacitor-filtered rectifier is connected
to a three-phase UPS system is proposed. Inrush current can be greatly reduced when digital
control with inrush current suppression loop in addition to observer, voltage drop compensator
and PID controller is applied to the system. Transient responses of UPS output voltage and load
current when the load is connected are shown, and the usefulness of the proposed control is
verified with simulations and experiments. |
