ARCHITECTURE OF DRIVE UNIT EMPLOYING GALLIUM NITRIDE SWITCHES |
摘要 |
A drive unit for a motor includes a printed circuit board (PCB); a first gallium nitride switch having a gate, the first gallium nitride switch mounted to the PCB; a second gallium nitride switch having a gate, the second gallium nitride switch mounted to the PCB; a gate driver generating a turn-off drive signal to turn off the first gallium nitride switch and turn off the second gallium nitride switch; a first turn-off trace on the PCB, the first turn-off trace directing the turn-off drive signal to the gate of the first gallium nitride switch; and a second turn-off trace on the PCB, the second turn-off trace directing the turn-off drive signal to the gate of the second gallium nitride switch; wherein an impedance of the first turn-off trace is substantially equal to an impedance of the second turn-off trace. |

1. A drive unit for driving a motor, the drive unit comprising:
a printed circuit board; a first gallium nitride switch having a gate terminal, drain terminal and source terminal, the first gallium nitride switch mounted to the printed circuit board; a second gallium nitride switch having a gate terminal, drain terminal and source terminal, the second gallium nitride switch mounted to the printed circuit board; a gate driver generating a turn-off drive signal to turn off the first gallium nitride switch and turn off the second gallium nitride switch; a first turn-off trace on the printed circuit board, the first turn-off trace directing the turn-off drive signal to the gate terminal of the first gallium nitride switch; and a second turn-off trace on the printed circuit board, the second turn-off trace directing the turn-off drive signal to the gate terminal of the second gallium nitride switch; wherein an impedance of the first turn-off trace is substantially equal to an impedance of the second turn-off trace. |
