摘要
传统的电流源应用中,需要保证电路不能出现阻断状况。使用Z源的电流源不仅允许电路出现阻断状况,而且通过对电路的控制实现电流的升降。本文对电流源的Z源拓扑结构进行了分析,并推导了其输入输出的关系式。同时将这种拓扑结构运用在了基于SHE-PWM控制的单相电流源逆变器上。以及运用MATLAB/SIMULINK工具对分析进行了仿真验证,以此说明这个电路的特性。
In the application of traditional current source, the status of circuit block is not allowed. Using Z-source current not only allows the block of circuit, but also implements lift current by controlling the switch. In this paper, the topology of Z-source is analyzed, and the relation of output and input is deduced. The topology is applied in current source inverter that is based in the control of SHE-PWM. MATLAB/SIMULINK is also used to simulate and test, illustrating the characteristics of the circuit.
