摘要
比较了车载逆变器传统推挽升压电路及其改进型,稳态分析了改进型拓扑,并进行了仿真验证。通过对变压器元件损耗分析,提出了变压器优化设计。试验验证表明,设计方案有效减小了变压器的损耗,提高了车载逆变器的效率。
Vehicle inverter converts 12 V DC power supply on a car into 220 V alternating current, the front stage usually adopts the push-pull circuit. In traditional push-pull circuit due to the presence of an output filter inductor, will increases the volume and loss. In order to solve this problem, the improvement of the push-pull circuit eliminates the output filter inductance. At the same time, the simulation verification was carried out. This paper will reduce the transformer loss to improve efficiency by analyzing the transformer losses, selecting the optimal foil thickness and the core.
