| Abstract: | The structural features and operation principle of power MOSFET are described simply,and the influences of temperature on key parameters,such as threshold voltage,transconductance,on-resistance,drain saturation current and breakdown voltage are analyzed theoretically.The blocking and conducting characteristics of power MOSFET at different temperature are simulated by ISE simulator.The variation curves of these parameters with temperature are given.Finally,the influence of temperature on safe operation area(... |
