摘要
提出一种新型的组合式正弦波高频链逆变器,与传统高频链或带Boost升压环节的DC/AC逆变器相比,在成本不增加的前提下,提高了效率。文中给出了详细的理论分析并做出了相应的比较。4kW、165V直流输入,220V交流输出的样机实验证实了所提方案的优越性。
A compositive, sinusoidal, high-frequency （HF） link inverter is proposed in this paper. The detailed theoretical analysis is given and the related comparison is carried out. Compared with the conventional HF link inverter or the DC/AC inverter with a Boost DC/DC stage, the efficiency is improved a lot, while the cost does not increase. And the feasibility is verified through the experiments on a 4kW 165V/220V prototype.
