FIELD: converter equipment.
SUBSTANCE: present invention relates to converter equipment; it can be used for control of IGBT transistor, including a power IGBT transistor. A driver contains a power supply source, a logic unit, a saturation protection unit, an output amplifier, an under-voltage protection unit, an overheating protection unit. For provision of protection of power IGBT transistors in overload and load short circuit, the driver additionally includes RC circuit, a support voltage source, a gate-emitter of the controlled IGBT transistor, equal to threshold voltage, a voltage comparator with an open collector output, a shunting resistor, a current-limiting resistor, Zener diodes.
EFFECT: provision of protection of power IGBT transistors in overload and load short circuit.
