High-precision IGCT Gate Pulse Drive Control: Built-in high-speed pulse shaping circuit, outputs stable amplitude & timing gate trigger signals for IGCT stacks, adjustable pulse width and dead time to guarantee safe and efficient rectifier/inverter power conversion of medium voltage converters.
Fiber Optic Isolated Signal Transmission: All control commands and fault feedback use fiber optic communication to completely isolate low-voltage control side and high-voltage power loop, eliminate EMI interference and ground potential difference damage.
Multi-dimensional Real-time Power Unit Monitoring: Onboard sampling circuit collects IGCT junction temperature, snubber circuit voltage, DC link ripple current and gate loop abnormal current; upload all monitoring data to main controller via fiber bus in real time.
Hardware Fast Protection Interlock Logic: Independent hardware protection loop without CPU delay, instantly block gate pulses when detecting overcurrent, short-circuit, overtemperature, gate drive power loss, avoid catastrophic damage to expensive IGCT power stacks.
Multi-channel LED Fault Diagnostic Indicators: Front panel dedicated LED status lamps for drive power, fiber communication link, overtemperature, overcurrent and gate abnormal faults, maintenance technicians can rapidly locate power unit faults without oscilloscope testing.
Wide-range Auxiliary Power Adaptation: Operates on standard cabinet internal auxiliary DC power, built-in EMI filter and voltage fluctuation suppression circuit to adapt unstable heavy industrial cabinet power supply.
Integrated EMC Surge Suppression Circuit: Every signal and power port equipped TVS and LC filter components, resist high-energy surge impact from medium voltage grid switching.
