has anyone understand out how to raise the maximum voltage? I need 75v
this is my electric 106 project.

I want to make a three-phase charger to connect to the 22kw columns. I want to use 6 huawei rectifier. I would like to change them to 75v to put 3 in series and make 225v. And three more in parallel to have double the current. When I find a 11kw column with orion2 bms with the canbus it lowers the current. I just have to understand the modification to get 75v.
Or I could connect 6 , 41v rectifier in series and do the 246v and with some diodes in series I lower the voltage due to the drop of 0.7v for each diode, there are 12, I put 24. what do you recommend?
Mr.: Huawei R24050G1 plus Bluetooth control module is more suitable for your needs.
Huawei R24050G1 is a high-efficiency, high-power density AC-DC rectifier module that supports three-phase voltage input from 260V AC to 530V AC, a rated output of 270V DC, and an output power of 15kW. The rectifier module adopts an isolated CAN communication interface, and the communication with the monitoring module adopts the CAN communication protocol. Through the monitoring module, the rectifier module can realize functions such as voltage regulation, current limiting, and single-module switching.
