Power Conversion:
o In frequency converters, it can convert alternating current (AC) with a fixed frequency into AC with a variable frequency, realizing precise control of the motor speed. It is widely used in the speed control of equipment such as industrial automation, fans, and pumps. It can improve the operating efficiency of the equipment, reduce energy consumption, and achieve soft start and soft stop, reducing the impact on the motor and mechanical system.
o In UPS (Uninterruptible Power Supply) systems, it converts direct current (DC) into AC. When the mains power is normal, the UPS rectifies the mains power into DC to charge the battery and then converts the DC into AC through inversion to supply power to the load. When the mains power is interrupted, the UPS quickly switches to the battery-powered mode and converts the battery's DC into AC through the inversion function of the IGBT module to ensure continuous and stable power supply to the load.
o In solar inverters, it converts the DC generated by solar panels into AC so that the electrical energy generated by solar power can be integrated into the grid or used for local loads. The high-efficiency conversion characteristics of this module help to improve the overall efficiency of the solar power generation system and make full use of solar resources.
o In wind inverters, it converts the unstable AC generated by wind turbines into stable AC so that it can meet the grid connection requirements and achieve grid-connected operation of wind power generation, promoting the effective utilization of renewable energy.
Circuit Control and Switching:
o As a high-performance switching device, it can quickly and accurately control the on-off state of the circuit. In various power electronic devices, according to the control signals of the system, it can quickly turn on or off the circuit to realize precise control and distribution of electrical energy.
o Due to its fast switching speed and low loss, it can be applied to high-frequency circuits, such as high-frequency induction heating equipment and electric welding machines. It can efficiently control the energy transmission of the circuit, improving the working efficiency and performance of the equipment.
Overcurrent Protection and Fault Isolation:
o When an overcurrent fault occurs in the circuit, the IGBT module can quickly cut off the circuit to prevent excessive current from causing damage to the equipment and system. Its fast response ability and reliable protection function can effectively avoid safety accidents such as fires and equipment burning caused by overcurrent.
o In a multi-module parallel or complex circuit system, if a certain module or part of the circuit fails, the IGBT module can isolate the faulty part from the normally working part, reducing the impact range of the fault and facilitating the fault diagnosis and repair of the system.
