摘要:本文分析研究了单周期控制单/双向直流变换器高频环节逆变器电路拓扑、控制策略、稳态原理与关键电路参数的设计。直流变换器型高频环节逆变器由直流变换器与极性反转逆变桥级联而成,具有电路结构简洁、前级工作在SPWM、后级工作在工频方波逆变、逆变桥功率开关电压应力低且实现ZVS、抗输入电压扰动能力等优点。仿真结果证实了这类逆变器理论分析的正确性。

Abstract:Analyzing and researching the topology of circuit,the strategy of control,the theory of steady state and the design of key parameters of high-frequency link inverter based on one-cycle control belonging to the type of single/bidirectional direct current convertor.High-frequency link inverter belonging to the type of direct current convertor is made up of direct current convertor and polarity reversal inverter bridge.It has many advantages,such as concision of circuit structure,the former grade working at SPWM mode,the later grade working at working frequency quadrate wave inverter,low voltage stress of inverter bridge's power switch and achieving ZVS,high ability of resisting input voltage disturbing,and so on,The simulation result demonstrates the correctness of this type of inverter.
