Current regulation
The equipment converts the single phase input voltage line into a rectified current and voltage. Then, the
equipment converts this DC current and voltage into a pure sine wave with a defined power rating.
Main feedback loop
The output measure PCB sends the measured output to the CPU PCB. Depending on the output, the CPU
PCB automatically generates a signal to adjust the regulation.
