简单地说，逆变器就是一种将低压（12或24伏）直流电转变为220伏交流电的电子设备。因为我们通常是将220伏交流电整流变成直流电来使用，而逆变器的作用与此相反，因此而得名。我们处在一个“移动”的时代，移动办公，移动通讯，移动休闲和娱乐。在移动的状态中，人们不但需要由电池或电瓶供给低压直流电，同时更需要我们在日常环境中不可或缺的220伏交流电，车载逆变器就可以满足我们的这种需求。
Simply put, the inverter is a low-pressure (12 or 24 volt) DC into 220 volts AC electronic devices. Because we usually 220 volts AC is rectified into DC to use, and the role of the inverter contrast, hence the name. We are in a "mobile" era, mobile office, mobile communications, mobile leisure and entertainment. In moving state, people not only need a battery or battery low voltage DC supply, but also need in our daily environment integral 220 VAC, car inverter to meet this demand we.
