High Frequency Induction Heating Equipment Metal Hot Forming And
Heat Treatment Equipment
Overview of high frequency induction heating equipment:
The high-frequency heater adopts a series resonance circuit, and
the circuit structure is as follows: after resonance, the
high-frequency power supply with low voltage and high current is
output through the high-frequency transformer; 15kw and 25kW
equipment are * products of our company. MOSFET power devices are
used for 15kw power and IGBT power devices are used for 25kW power.
The inverter control technology of our company is adopted. The
equipment structure is very simple, the reliability is high, the
maintenance rate is low, and it is convenient for customers to
maintain by themselves. It is one of the most widely used equipment
at present
