研究了一种以热电发电器件为输入源的变流装置。变流器为三相交错控制Buck级联Boost电路结构。根据输入输出电压的变化，变流器可以工作在Buck电路模式或者Boost电路模式。根据负载蓄电池状况，变流器有最大功率跟踪和功率匹配两种控制模式。分析了三相交错控制技术对输出纹波电流的影响。设计了变流器的控制环。对实验室样机的测试表明，变流器能在Buck和Boost模式之间，以及最大功率跟踪模式和功率匹配模式之间平滑切换。

This paper discusses the converter sourced by thermoelectric generators, which is a kind of three-phase interleaved buck cascaded boost converters. According to voltage changes of input source and output source, the converter can operate in either buck mode or boost mode. Based on battery status, the converter has maximum power tracing (MPPT) mode and power match (PM) mode. The effect of three-phase interleave tech-nique on output ripple current is then analyzed, and the controller of the converter is thus designed. The testing results show that it can transfer smoothly between buck mode and boost mode, and between MPPT mode and PM mode.
