Ventilation systems are one of the most important and energy-consuming systems in the manufacturing process of modern mining enterprises. Variable-frequency asynchronous and synchronous electric drives with frequency converters based on self-commutated inverters or variable-frequency synchronous electric drives based on the LCI scheme are considered as advanced drives for ventilation units. When upgrading electric centrifugal fans with slip-ring asynchronous motors and unexhausted performance potential, it is effective to apply a wound-rotor slip-recovery system. A converter with natural commutation with an intermediate dc link is used in the LCI scheme. Robicon frequency converters are used for variable-frequency high-voltage electric motors. An important advantage of these converters is that they can be used for standard 6- and 10-kV motors.
