摘要:
传统Z源逆变器最大恒定升压控制策略能够在任意给定调制比下获得最大的电压增益,电感中不含有与输出频率有关的电流纹波。针对该升压控制策略导致开关频率增倍,而且需要额外的数字逻辑器件辅助实现的问题,提出一种改进型最大恒定升压控制策略,在SVPWM的基础上,通过调整同桥臂的开关管开通、关闭时刻,实现直通的插入。与传统最大恒定升压策略相比,该调制不仅能够有效降低开关频率,还能够在单周期内插入6段直通状态,增加电感电容充电频率,从而减小Z源网络中组件体积。另外,在该调制策略下电容电压是恒定的,能够有效减小在高直通比时电容电压应力。通过仿真和实验结果验证了改进型最大恒定升压调制策略的优点。
Abstract:
The traditional maximum constant boost control of z-source inverter can obtain the maximum voltage gain at any given modulation index without any low-frequency current ripple in the inductors.But the switching frequency is doubled,and additional digital logic is needed for realization.A novel constant boost control is proposed.Based on SVPWM,the shoot-through zero states was inserted by changing turning on or off time of the same bridge switches.Compared to the traditional maximum constant boost...
