Introduction of Medium Frequency Power Supply
A medium frequency power supply is that converts a three-phase power current into a single-phase if current and causes the heated metal to produce eddy currents by electromagnetic field induction for heating and melting. The inverter series circuit charges the capacitor through the reactor to ensure the inverter has a stable voltage output. At the same time, due to the existence of capacitance, it can prevent the inverter high harmonic feedback to the power grid, so there is no harmonic harm to the power grid. Besides, the equipment is the rectifier full output circuit, the power factor is always above 95%. Series inverter adopts frequency modulation and power adjustment, that is, the equipment power is regulated by changing the inverter frequency, the rectifying part of the thyristor is completely in the open state, inductance, and capacitance filtering, unlike parallel resonance to adjust the DC voltage to adjust the output power. In the process of intermediate frequency electric furnace drying and later insulation, the thyristor is still in the fully open state, which greatly improves the power factor of the equipment, so the voltage output is stable and prevents the pollution of the power grid by higher harmonics.
Product features of Medium Frequency Power Supply
● The thyristor is fully open, which greatly improves the power factor of the equipment.
● In the case of low incoming voltage, high voltage can be obtained on the induction coil. The same power maximizes the resonant current in the induction coil, thus reducing the power consumption.
● After the start by changing the frequency, change the inverter Angle regulation power. So the power will start up 100% successfully.
● Two or even more inverter Bridges can be installed under one rectifier bridge, which is convenient for a set of power supply with two or even more electric furnaces, and the power can be distributed arbitrarily among each furnace body.
● A simple circuit, reliable operation, convenient adjustment, strong adaptability to load, a wide range of adaptation.
● The fully integrated control circuit, with over-voltage, over-current, inverter failure, insufficient water pressure, and other protection functions.
● Modular design for easy maintenance. The important parts adopt the international brand, the whole machine life is up to 10 years.
