| Summary: | 碩士 === 國立臺北科技大學 === 電機工程系研究所 === 100 === This paper is aimed to design a single-phase full-bridge converter with bi-directional power flow control. The converter not only produce reactive power of compensation but the converter have storage battery which can apply as uninterruptible power supply (UPS). On other hand, the converter can also supply transient power for load that can mitigate grid’s overload danger. The converter based on a bi-directional buck/boost dc-dc converter series bi-directional single-phase full-bridge converter and storage battery connected a buck/boost dc-dc converter of low voltage side. For fast dynamic response, this paper design single-phase full-bridge converter of current controller based on small signal analysis and subsequently establish DC-DC converter connected storage battery of current controller as small signal model that and design high bandwidth of current loop by referring to this model. And made proposed converter’s current bandwidth up to 1 kHz.
A single-phase full-bridge converter controlled by a DSP-TMS320F28035 with 110V/1 kW is constructed and uses single-phase induction motor as transient load. To realize the digital control, all the controlling strategies are written by software. Proposed method can verify by experiment and it improve induction motor of starting current that cause grid’s voltage drop efficiently.
