    MF100 Series Medium-frequency Power Supply Safety precautions  Do not refit the medium-frequency power supply unauthorizedly; otherwise fire, electric shocks or other injury may occur.  The base may become hot when the machine is running. Do not touch them.

  • Page 7: Chapter 2 Product Overview

    Chapter 2 Product overview 2.1 Basic principle MF100 series medium-frequency power supply is a kind of device which converts 1PH or 3PH fundamental frequency power supply into 1PH medium-frequency power supply. The main circuit diagram is shown as below. The rectifier circuit converts AC voltage into DC voltage, with the capacitor bank in the middle serving for energy storage and filtering, and then converts DC voltage into AC square-wave voltage through the inverter circuit.
