Three Suggestions To Help You Improve The Efficiency Of The Inverter - Prostar Inverter

On the problem of hybrid solar inverter efficiency, designers have always been committed to improving the efficiency of the solar inverter. But which areas to start, so as to improve the efficiency of the inverter?

For the inverter with transformer, the main DC filter main circuit (or DC filter circuit), IGBT (or other inverter module), reactor, transformer, AC filter (or homemade filter circuit and wire). So in order to improve the conversion efficiency of the inverter, we can start from these aspects. For example:

1.IGBT, we can reduce the IGBT loss, reduce the switching frequency of the IGBT, but also cannot be reduced without limit, because when reducing the switching frequency, the waveform of the pure sine wave solar inverter will be worsen, the power quality will be reduced, and will increase the noise of the machine, so can only be appropriate to reduce the switching frequency of IGBT.

2.The loss of the transformer. While the transformer losses only the copper loss and iron loss, when we reduce these two loss, inverter conversion efficiency will be improved.

3.The loss of reactor, the reactor to improve the Q value, which is to reduce the inductance of the inductor. So many ways to improve the conversion efficiency of the inverter, I believe that experts in this area will have a lot of more effective methods to improve the efficiency of the products.
