A Novel Gate Driver with Output Possessing Triple Input Voltage and Negative Double Input Voltage

This paper presents a gate driver, whose output possesses the triple input voltage and the negative double input voltage under only one positive-voltage source required. Such a gate driver can reduce the transient period of the gate driver and hence can reduce the corresponding switching loss. In addition, since double the negative input voltage is imposed on the input of the power switch during the turn-off period, not only the error in triggering the switch due to the Miller effect can be reduced, but also the leakage current can be reduced. The detailed operating principles are illustrated and some simulated and experimental results are provided to verify the effectiveness of the proposed scheme.
