ABSTRACT:
A full bridge driver includes a control chip outputting a first control signal and a second control signal, a full bridge switch assembly with four N-MOSs coupled to a DC power, a first side of a transformer, and two drivers. Moreover, one of the two drivers includes a first cut-off switch that turns off the first N-MOS in response to the first control signal, a first charging path coupled between the DC power and the second N-MOS, a first discharging path coupled between the gate end and the source end of the first N-MOS. Furthermore, another one of the two drivers includes a second cut-off switch that turns off the third N-MOS in response to the second control signal, a second charging path coupled between the DC power and the fourth N-MOS, and a second discharging path coupled between the gate end and the source end of the third N-MOS.
