定义
Power semiconductors are solid-state electronic components designed to handle high voltages and currents, used for switching, amplifying, and regulating electrical power in power conversion systems. They operate as switches or amplifiers in power electronic circuits, enabling efficient control of electrical energy in applications like motor drives, power supplies, and inverters.
工作原理
Power semiconductors operate based on semiconductor physics, using materials like silicon or silicon carbide. They function as electronic switches by controlling the flow of current through semiconductor junctions (e.g., PN junctions in diodes, MOSFETs, or IGBTs). When a control signal (voltage or current) is applied, the device switches between on (conducting) and off (non-conducting) states, enabling precise power modulation with minimal losses.
