| 中文摘要 | 提出了一种新型的隔离型双向软开关DC/DC变换器。变换器中的开关元件能够在全负载范围内实现软开关并且二极管实现零电流关断。上述措施有效地减少了开关损耗,电磁应力和电磁干扰。在简要介绍变换器工作原理的基础上,本文着重分析了电压、电流的变化规律,特别是推导出各开关元件实现软开关的条件及其数学表达式,并得到了实现软开关的通用条件。试验结果证明根据该通用条件设计的实验样机能够在大负载范围内实现软开关。; A novel zero voltage switching (ZVS) bi-directional DC/DC converter is presented, which can achieve ZVS for all switches in the whole load range. Besides, the diode reverse recovery is also diminished with zero current switching (ZCS). These measures reduce switching losses, current and voltage stresses and electromagnetic interference (EMI). Operation principle of the proposed converter is introduced. The soft switching principle is also introduced briefly. On the basis of the operational analysis, the characteristic of the voltage and current is illustrated and the ZVS condition of the different switches are also given in detail. What is more, the formula of the universal ZVS condition for all the switches is specially deduced to simplify the four ZVS conditions into one formula for the convenience of the design . Experimental results obtained from a 500W prototype are also shown to verify the validity of the universal ZVS condition. |
