| Zusammenfassung: | The invention relates to a system and a method of driving a power transistor. The system for driving the power transistor comprises a ratio conversion circuit and a switch driving circuit, wherein the ratio conversion circuit is configured to use a first conversion ratio or a second conversion ratio to convert a first characterization signal for characterizing current passing through the power transistor to generate a second characterization signal based on a first control signal; and the switch driving circuit is configured to generate driving signals for controlling on and off of the power transistor based on a second control signal, a third control signal and the second characterization signal. |
