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。
They will randomly move in all directions but that isn’t any use to us. We'd like numerous electrons to maneuver in a similar direction. We do that by applying a voltage big difference throughout the wire, the voltage is like pressure and will press the electrons.
Inverters squander Power converting DC electricity to AC, and there are numerous other losses in ability technology and distribution, so why not merely supply small-voltage DC electrical power to houses to begin with?
双极性调制只需要一个比较器就行，简单易实现，单极性调制则需要两个比较器，如下图所示：

The modified sine wave inverter makes a waveform that approximates a sine wave but with some distortion. It is much more appropriate with most appliances and equipment when compared with sq. wave inverters and is often Utilized in residential and automotive apps.
With single stage We've got a link to only an individual stage from the generator, so We have now only one sine wave. But with three period electric power We have now a Sunsynk Powerlynk South Africa relationship to every of your 3 phases. The phases are coils of wire which can be inserted into your generator 120 degrees besides the former, This implies the coils practical experience the height with the rotating magnetic industry at various situations, this gives us our three phases, Just about every with a unique sine wave that's somewhat away from sync with the preceding.
前面的说的是单桥臂工作情况，虽然用的极少，但是对于了解复逆变器是很有帮助的。比如，我们再增加一个桥臂，就可以组成一个单相桥电路，如下图所示。
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：
