摘要
整流滤波电路用途广,消除电感器直流偏磁的影响已成为研究的热点。将电感器由直流侧挪至交流侧,可消除电感器的直流分量,但其动静态特性的分析和优化设计也更加复杂。该文对不控整流电路进行分析,利用5维可视化展现两种情况下瞬态电压和电流的变化过程,仿真和实验均表明,采用交流电感器时振荡电压低浪涌电流持续时间短,电感器位于交流侧时铁心利用率高,在稳态滤波效果大致相同的条件下,体积比位于直流侧的电感器小,两者之比约为1/2。
The rectifier filter circuit is widely applied. However, how to counteract the dc bias produced by inductor current has become a research tendency. By moving the inductor from dc side of rectifiers to ac side, the dc component can be eliminated directly, but the analysis and optimization design of dynamic characteristics are more complex. Mathematical analysis of the transient of the single-phase diode rectifiers is presented. Using 5D visualization, the changing processes of transient voltage and transient current in the two different cases can be showed, and it is proved that the surge voltage is lower and the duration of over current is shorter; And the core utilization will be much higher by using AC inductor than DC inductor. In the circumstances of same steady-state output, the volume of AC inductor is smaller than the DC inductor. The result indicates that the volume ratio of them is approximately 1/2.
