Research And Design Of 6KVA AC/AC Inverter

With the development of the electronic technology,the higher requirements of Power Supply are raised including high efficiency,high power density,low EMI and rapid dynamic response. A Hysteresis-band instantaneous current control PWM technique is popularly used because of its simplicity of implementation,fast current control response,and inherent peak current limiting capability. This paper presents a novel single phase aeronautical static inverter. A novel combining two-transistor forward converter is presented and applied in the front of three-level hysteresis current controlled inverter,and a single-phase 6KVA aeronautical static inverter is developed.This paper mainly describes the small signal model and properties of the DC/DC converter,the optimum control model of the DC/AC inverter and analyses the stability and dynamic characteristics of the system . The experimental results show that the static inverter achieves high performance target.
