I am required to make a battery charging circuit for a high frequency sine wave inverter, rated 12V/230V, 850VA
Target battery size is 100AH to 180AH. And thus charging current capability of upto 20A is desired.
There is a HF transformer on board, how can this be utilized to charge the battery, without using an additional H-Bridge. I am having difficulties in getting the X-mer rest.
I have another idea of using a buck converter, switched with a low voltage drop IGBT (FGD4536
360 V PDP Trench IGBT). This IGBT is cheap and has a voltage drop of approx 1.3V @ 25A. Although I am not very reluctant about using the buck converter for step-down ratio as high as 1:20 at a current level of 20A. But there doesn't seem to another way.
Please give suggestions
