Features of power semiconductor devices
1. The ability to handle electrical power, that is, the ability to withstand voltage and current, is the most important parameter.
2. Power electronic devices generally work in the on-off state.
3. In practice, power electronic devices often need to be controlled by information electronic circuits. For example, lithium battery manufacturers use them to control the battery.
4. In order to ensure that the device is not damaged due to excessive heat caused by the heat dissipated by the loss, not only the heat dissipation design is emphasized on the device package, but a heat sink is generally installed when it is working.
