RESONANT CURRENT INVERTER FOR INDUCTIVE HEATING ON IGBT
Purpose of the development:
It is intended for operation as a unit component together
with parallel resonant LC circuit for heating, smelting and
thermal treatment of raw and work materials.
It allows to operate together with circuit at resonant
frequencies of 1-25 kHz with capacity not more than
30kW. Resonant current converter provides manual mode
of inversion frequency or automatic adjustment of
inversion frequency to resonant frequency of operating
circuit. It also performs output power control in the range
of 0-100%.
Technical characteristic:
Technical characteristics:
. Power supply: three-phase network 380V/50Hz.
. Maximum capacity: 30 kW.
. Output frequency range: 1 - 25 kHz
. Maximum output voltage value: 500 V.
Output current and output voltage protection facilities
are provided
. Temperature protection: the temperature on 85°R can cause emergency shutdown.
• Cooling: forced air cooling
• Power supply of control circuit and forced air cooling ventilators is performed through alternating current network (220 V, 50 Hz).
