新能源汽车DC/AC变换电路教学模型设计

Design of Teaching Model for DC/AC Conversion Circuit of New Energy Vehicles

DC/AC变换电路作为新能源汽车上的核心电路之一,在实车上,由于集成度高、高电压等特性,非常不利于初学者进行学习。本文中设计的DC/AC变换电路教学模型,学生不仅能直观认识其主电路和控制电路的结构,而且还能通过预留的接线端子进行电路再次搭建和测量其关键信号线上的电路参数,进而快速掌握DC/AC变换电路的基本结构和工作原理,为后续实车故障诊断打下较好的基础。

As one of the core circuits in new energy vehicles,the DC/AC conversion circuit is not conducive to beginners'learning in real vehicles due to its high integration and high voltage characteristics.The DC/AC conversion circuit teaching model designed in this article not only allows students to have a direct understanding of the structure of the main circuit and control circuit,but also to rebuild the circuit and measure the circuit parameters on its key signal lines through reserved wiring terminals,thereby quickly mastering the basic structure and working principle of the DC/AC conversion circuit,laying a good foundation for subsequent fault diagnosis in actual vehicles.
