Trends of Power Semiconductor Devices for Power Supply

Power Supply and Current Modulation Circuits for Semiconductor Lasers

Design and construction of a stable current supply with protection circuits are described. The reported circuit provides a high-stable and high-level current variable from 0.5-1.2 A with the protect ion circuits to prevent over load current, voltage and off-range temperature operation. A detailed analysis of the circuit parameters is given and the time behaviors of the load voltage/current and ...

Power Semiconductor Devices

Classification, essential properties, important applications and developement of power semiconductor devices will be explained. Some common power semiconductor devices, power metal oxide semiconductor field-effect transistor (MOSFET), thyristor and some new power devices will be described and discussed.

Present Status and Trends of Power Semiconductor Devices

The curtain has been raised on new century. Prior to discussing the present status and trends of power semiconductor devices, allow us to briefly review Fuji Electric’s history with power devices. The semiconductor device was invented and developed in the latter half of the 20th century. When Shockley, Brattain, and Bardeen invented a transistor in 1948, they did not think that this transistor ...
