摘要
基于PWM控制的推挽式DC-DC直流升压电路的系统结构,设计了一种适用于小功率逆变的直流升压电路。该电路采用两组推挽电路叠加的升压方式,转换效率较普通的反激电路高,对器件的参数要求不高。实验结果表明设计可行可靠。
A DC-DC boost circuit based on PWM control and push-pull structure for a small power inverter is presented in this paper. The whole system is mainly composed of two series connectect push-pull circuits with superimposed boosted mode. Conversion efficiency of this circuit is more than ordinary flyback circuit and the requirement for device＇s parameters is relaxed. The experimental results confirm the feasibility and reliability of the design.
