Abstract-In this paper, a novel DC-AC single phase inverter is
proposed. When the switches are turned on and off, a conventional
inverter generates switching loss because of the hard switching.
Thus, the inverter loss is increased. Proposed system contains
auxiliary circuit. The converter stage switches perform
soft-switching because of the auxiliary circuit. Also inverter stage
switches perform ZVS when the dc-link voltage is zero. Therefore
all switches perform soft-switching when the switches are turned
on and off. Thus the proposed system reduces switching loss and
voltage stress.

引言—本文意旨提出一種新穎的DC - AC單相逆變器的建議。當(dāng)開(kāi)關(guān)開(kāi)啟和關(guān)閉的時(shí)候，傳統(tǒng)的硬件逆變器開(kāi)關(guān)會(huì)產(chǎn)生物理?yè)p耗。因此變頻器的損耗就大大的增加了。本文建議在變頻器的電路系統(tǒng)中可以增加一個(gè)輔助的電路，這個(gè)輔助電路用軟件來(lái)執(zhí)行交替開(kāi)關(guān)。另外，當(dāng)直流母線的電壓為零時(shí)，變頻器開(kāi)關(guān)執(zhí)行零電壓階段。因此將所有的開(kāi)關(guān)換成由軟件來(lái)控制的開(kāi)關(guān)之后，整個(gè)系統(tǒng)可以降低其由開(kāi)關(guān)帶來(lái)的硬件損耗和損失的電壓應(yīng)力，變得更節(jié)能了。
