摘要
双Buck逆变器具有抗桥臂直通,可靠性高等优点。滞环电流控制是一种典型的非线性变频电流型PWM调制技术;而双极性SPWM调制系统属于恒频线性控制。这里给出了基于双Buck逆变器的滞环电流控制和双极性SPWM控制的两种实验结果比较;进行了50～400Hz宽变频实验研究,使双Buck逆变器既能用作航空静止变流器,又可并网用作民用电。
The dual-buck inverter has the advantages of high-reliability, freedom from shoot-through problems.Hystere- sis current control is a typical kind of non-linear and variable frequency control method,while bipolar SPWM is linear and its frequency is uniform.This paper gives a comparison of experimental results between these two control methods in dual- buck inverter.And it also researches the 50~400Hz wide variable frequency experiments,which enable the dual-buck in verter be used as aeronautical static inverter and connect the zrid to be civil electricitv.
