| Abstract: | Uninterruptible Power Supply (UPS) has been applied in many fields. The designing purpose of UPS is introduced in this paper. Based on the analysis of some pivotal techniques for UPS, a novel scheme of fully digitized control system based on DSP (TMS320F240) is proposed. The principle and performance of phase lock loop are especially analyzed and the method used for fast voltage detection is presented for the digital- controlled UPS, which are used for supplying the load uninterruptedly. These methods are very simple and practical. The experimental results demonstrated that the practical system could achieve good dynamic and static performances. |
