The upstream of the industrial automatic control system device industry chain primarily comprises components such as chips, semiconductors, electronic components, permanent magnet materials, insulating materials, and structural parts.
Frequency converters are power control devices that utilize frequency conversion technology and microelectronics to control AC motors by altering the frequency of their operating power supply. By controlling the motor speed, they enable energy-saving and precise process control. The IGBT module is a critical component in frequency converters, and its selection and loss directly relate to the size of the heat sink, also significantly impacting system performance, cost, and size.
The efficiency and stability of electric welders directly influence welding quality. The IGBT module, as the core component in electric welders, primarily controls the flow of current to achieve precise welding.
Renewable Energy - Photovoltaic, Wind, Energy Storage, SVG, APF, UPS
Against the backdrop of "carbon neutrality," the proportion of photovoltaic and wind power in the energy mix is gradually increasing, and energy storage is experiencing favorable development globally.
IGBT power devices serve as the core semiconductor components of photovoltaic inverters, wind power converters, and energy storage converters, rectifying and inverting electrical energy to facilitate AC grid connection of renewable energy power generation and charging and discharging of energy storage batteries. Static Var Generators (SVG) and Active Power Filters (APF) application solutions are used to improve the quality of power systems. SVGs can adjust grid voltage and maintain voltage stability, while APFs reduce harmonics and grid pollution, enhancing power quality. Uninterruptible Power Supply (UPS) systems are critical devices that ensure continuous power supply to essential equipment during grid failures.
Electric-Vehicles
lectric vehicles (EVs) use onboard power sources as their motive force, with motors driving the wheels. They are widely favored due to their relatively lower environmental impact compared to traditional vehicles. Pure electric vehicles (PEVs) primarily differ from fuel vehicles in four components: drive motors, speed controllers, traction batteries, and onboard chargers.
IGBT devices are utilized in various systems of new energy vehicles, including thermal management, lighting, and charging inverter systems. IGBTs are the primary power devices for semiconductors in new energy vehicles. As carriers for electric energy conversion, IGBTs are widely used in the electric components of vehicles to complete DC-AC and voltage conversion, serving as the main power devices in motor controllers, inverters, EV charging piles, and other equipment.
