Abstract: A nov el aircr aft static inverter based on the distr ibution power conversion technology is presented in thisPaper- The inverter is composed of some unified print-circuit boards. No high voltag e pow er device is used in this inverter. T he shortcomings such as pow er conv er ted concentrated and makeup complex ity are tided over-The newsystem is composed of four push-pull forward conv erters and one four stage cascaded inv er ter. The operation pr inciple and control scheme of the new system are analy zed. The ex periment results in that the novel static inverter isw ith the merits of high efficiency , high output voltage quality, hig h r eliability and ease realization.
