The IGBT module is the core power switching device inside an industrial frequency converter. Under the control of the drive circuit, it rapidly turns on and off large currents, enabling the frequency converter to convert the DC bus voltage into variable-frequency AC output. Our Igbt power module 1200v 600a adopts a trench gate/field cutoff structure and is equipped with an NTC thermistor. The data parameters of IGBT are not merely simple descriptions in the instruction manual; they directly determine whether the frequency converter can maintain operation under high temperatures, voltage transients, and long-term heavy loads.
With a larger voltage margin to cope with grid fluctuations
The industrial grid situation is complex. The 1200V insulated gate bipolar transistor (IGBT) can provide you with sufficient safety margin above the actual DC bus voltage, resisting some unexpected voltage shocks, protecting the chip from being broken and affected, and significantly reducing the possibility of failure during instantaneous overvoltage periods. The reduction in module failures leads to a decrease in the number of maintenance service visits.
Tolerance under faults
When dealing with loads or in the event of a fault, a 1200V 600A IGBT must have sufficient tolerance capacity to allow the driver sufficient time to respond and react. And our product has a strong short-circuit tolerance capability. This performance is particularly important for high current igbt modules because uneven current distribution may cause local current overload. Without short-circuit tolerance, a single fault could cause problems with the entire inverter. With it, the driver can safely shut down and restart.
Verification and design based on actual testing
The reliability of the product is determined by the data parameters obtained from complex testing procedures, rather than simple verbal commitments. We guarantee that before shipment, each batch of products will undergo performance igbt module testing, which simulates the operation of the product under high-intensity conditions. We will check the thermal resistance, the saturation voltage under temperature changes, and the repeated short-circuit durability. At the same time, we design an NTC thermistor inside the product to enable your system to monitor the contact temperature in real time. The copper substrate design ensures that the module will not crack under vibration, thermal shock, and high humidity. These tests and designs mean that the products we provide can operate stably and reliably for a long time.
Our company's 1200-volt, 600-ampere IGBT power module offers a wider voltage margin, lower conduction loss, high anti-interference short-circuit capability, and has passed comprehensive testing verification. It significantly enhances the reliability of industrial frequency converters. For the operators of frequency converters, this means a substantial reduction in emergency maintenance costs.
