【摘要】:為實(shí)現(xiàn)一種結(jié)構(gòu)簡(jiǎn)單、控制方便、高效率、高功率密度的逆變器,提出了一種新型諧振直流環(huán)節(jié)軟開關(guān)逆變器的拓?fù)浣Y(jié)構(gòu).通過(guò)在傳統(tǒng)硬開關(guān)逆變器的直流環(huán)節(jié)添加輔助諧振單元,使直流母線電壓周期性地歸零,可以實(shí)現(xiàn)逆變橋主開關(guān)器件的零電壓開關(guān),而且輔助開關(guān)器件可以實(shí)現(xiàn)零電流開通和零電壓關(guān)斷.此外,其輔助諧振單元只有一個(gè)輔助開關(guān)器件,所以該逆變器控制相對(duì)簡(jiǎn)單,硬件成本低.對(duì)其工作原理進(jìn)行分析,給出不同工作模式下的等效電路圖和軟開關(guān)的實(shí)現(xiàn)條件.制作一個(gè)1k W的實(shí)驗(yàn)樣機(jī),通過(guò)實(shí)驗(yàn)結(jié)果驗(yàn)證該軟開關(guān)逆變器的有效性.
[Abstract]:In order to realize a kind of inverter with simple structure, convenient control, high efficiency and high power density, a new type of resonant DC link soft-switching inverter is proposed. By adding auxiliary resonant unit to the DC link of the traditional hard-switching inverter, the DC bus voltage is periodically returned to zero, and the zero-voltage switch of the inverter main switch device can be realized. And the auxiliary switch device can realize zero-current turn-on and zero-voltage turn-off. In addition, the auxiliary resonant unit has only one auxiliary switch device, so the inverter control is relatively simple and the hardware cost is low. The working principle is analyzed, and the equivalent circuit diagram and the realization condition of soft switch under different working modes are given. An experimental prototype of 1kW is made, and the effectiveness of the soft-switching inverter is verified by the experimental results.
