Abstract
AC variable frequency control technology is an important development orientation of the transmission power of modern technology. With the power electronics technology, micro-electronics technology and modern control theory used in AC Frequency Control System, the converter as the core of it has been dramatically improved, and more widely used in industrial production and daily life in many areas.
In this paper, we have a simple overview to the General Convert and the exchange of technology, VVVF technology is also discussed. Summarized the development of the Convert, including its closely related to the power devices, control method and PWM control technology is also explained.
In this paper, the generic design for converter of single-phase input is DC-AC-DC voltage converter. The main circuit posed of Rectifier circuit, filter circuit and inverter circuit. Rectifier diode circuits use single-phase bridge uncontrollable rectifier module. Filter circuit uses electrolytic capacitor to filter; Inverter posed of six IGBT three-phase full-bridge inverter. Main circuit's structure is simple and easy. IR2103 is used as the driver of the IGBT. Relay control circuit is used as protection circuits. At the same time , there also have voltage, current detection circuit. After finish the design, the next step is welding all parts, and solves what is meeting in the expe
