A Medium Frequency (MF) Generator is a high-power electronic device that converts the standard line frequency (50/60 Hz) AC power into a high-current, medium-frequency alternating current (AC). Its primary application is to drive an induction coil for rapid, precise, and non-contact heating of conductive materials.
The medium frequency range typically spans from 1 kHz to 100 kHz, which is ideal for achieving deep, uniform heating in larger workpieces or for high-speed industrial heating processes.
Technology: Modern MF generators use high-power IGBT (Insulated Gate Bipolar Transistor) modules and advanced inverter control (often parallel oscillating circuits) to achieve high efficiency (typically $>90\%$) and reliable operation.
Control: Offers high precision control over output power, frequency, and time. This allows for programmed heating cycles, often with integration into automated production lines.
Cooling: Due to their high-power density, most industrial MF generators are water-cooled to maintain component stability and longevity.
