What are Power Semiconductors?
A semiconductor is a material characterized by its ability to act both as a conductor (allowing electricity to flow) and as an insulator (preventing its flow). It primarily serves the following three functions:
(1) Rectification: One-way current flow
(2) Amplification: Amplifying electrical signals
(3) Switching: Controlling the flow of electricity
Power semiconductors feature a specialized structure that enables them to handle high voltages and large currents without incurring damage. However, handling high power levels generates heat, and the resulting temperature rise can lead to device failure. To address this, significant effort has been made to reduce power loss—the root cause of heat generation—and to effectively dissipate heat away from the device.
Power semiconductors are primarily used in power conversion, such as adjusting voltages and frequencies or converting between AC and DC power. They play a critical role in controlling motors across all speed ranges, supplying solar power to grids with minimal energy loss, and providing reliable electricity to household appliances and electronic equipment.
As global focus on energy conservation and efficiency grows, the demand for high-efficiency power semiconductors continues to rise.
