中小功率逆变电源是户用独立交流光伏系统中重要的环节之一，其可靠性和效率对推广光伏系统、有效用能、降低系统造价至关重要?因而各国的光伏专家们一直在努力开发适于户用的逆变电源，以促使该行业更好更快地发展。
随着人们对城市环境的日益关切，电动汽车的发展得到了一个难得的机遇。在城市交通中，电动大客车由于载量大，综合效益高，成为优先发展的对象。电动大客车大都采用三相交流电机，由于电机功率大，三相逆变器中的器件需要承受高电压和大电流应力的作用，较高的dv/dt又使电磁辐射严重，并且需要良好的散热。
Inverters waste Power converting DC ability to AC, and there are lots of other losses in electric power era and distribution, so Why don't you just provide minimal-voltage DC energy to homes to start with?

Grid-tie inverters are specifically designed for connecting renewable Electrical power devices, which include solar panels or wind turbines, for the utility grid. They convert the DC electrical power generated via the renewable resources into synchronized AC ability which might be fed again for the grid or used domestically.
无源逆变器：使电流电路中的电流，在交流侧不与电网连接而直接接入负载（即把直流电逆变为某一频率或可调频率的交流电供给负载）的逆变器。

Imitate Sine Wave If we did that one hundred twenty times for each 2nd then we would get 60hz AC and when we did that 100 times for Best Hybrid Inverter South Africa every 2nd then we would get 50hz AC.
Inside a copper wire we discover copper atoms. These have electrons which often can move to other atoms, they're generally known as free electrons mainly because they are free of charge to move about.
We will control the output voltage by managing how long the switches are shut for. So, we could as an example output 240v or 120v by trimming the open up and close moments.
然而，缺点也显而易见，那就是逆变后交流端谐波分量很大。通常情况下，我们期望得到具有良好正弦性的波形，特别是对于交流电机控制，最好是理想的正弦波，因为基波之外的谐波不产生有效力矩，而是带来力矩的波动。
现在再来看一下相电压。我们知道，相电压为绕组端部相对于中性点N的电压，而我们已经知道绕组端部相对于电源接地点O的电压，我们把两者建立联系如下：
As We have now a very low voltage input, we’re going to get a small voltage output. To reach the 120V or 230V necessary to electricity our appliances, we will even need a transformer to move up the voltage to some handy stage.
