摘要
以实际工程为应用背景,应用先进的高频功率变换技术,研制出满足某型特种车辆使用要求的升压变换器。该变换器采用推挽式主电路拓扑结构和带逐脉冲比较控制的三闭环结构,通过优化电路参数,改进变压器绕制工艺和系统布局等技术措施,解决了变换器存在的偏磁和关断尖峰大等实际问题。此外,升压变换电源采用了模块化设计和冗余配置,有效地提高了系统可靠性。经实车使用证明,该装置具有体积小、重量轻、可靠和效率高等特点。
Taking ＂Ten-Five＂ pre-research project as the background, the boosting inverter which meets the demand of special vehicle is developed by using high-frequency power convention technique. This inverter uses push-pull main circuit and three closed-loops with comparable controlling in every pulse. By optimizing circuit parameters and improving transformer winding tech and system layout, the key problems such as magnetic deviation and high peak voltage are settled properly. Furthermore, this device is designed by modularity and redundance, the system reliability is enhanced. Through practical testing, the boosting inverter has the advantage of little volumes, light weight, high efficiency and high reliability.
