R3 DC/DC Converter for Frequency Converter Application

The host controller employs DSP, CPLD and FPGA as the core operation units, and data sampling, control units, optical communication loop, and the PLC as the control system.

For the DC from the transformer is still not stable, MORNSUN URB2415LD-20WR3 is suggested to power the 6×IGBT drivers with isolationpower the communication circuit and the signal processing circuit ,and avoid the interference among the modules.
