Drive acceleration circuit and circuit system

A circuit system, comprising:

• a switching device, which has a control end and a connection end;
• and
• a drive acceleration circuit, wherein the drive acceleration circuit comprises:
• a drive power supply, comprising an output end and a reference signal end, wherein the output end is configured to output a drive signal, and the reference signal end is coupled to the connection end of the switching device and is configured to output a reference signal to the connection end;
• a first signal route, wherein the first signal route is coupled to the output end of the drive power supply and the control end of the switching device, and is configured to drive, based on the drive signal, the switching device to turn on or turn off;
• and
• a second signal route, which is connected in parallel with the first signal route, wherein the second signal route comprises a drive acceleration unit and a selective conduction unit, one end of the drive acceleration unit is coupled to the output end of the drive power supply, another end of the drive acceleration unit is coupled to the control end of the switching device through the selective conduction unit, the selective conduction unit is turned on in a time division manner to make the second signal route closed or open, and the drive acceleration unit is configured to accelerate the turn on and turn off of the switching device based on the drive signal when the second signal route is closed;
• and
• the drive acceleration circuit is configured to drive the switching device to turn on or turn off, wherein the switching device has the control end and the connection end;
• and
• the drive acceleration circuit is coupled to the control end and the connection end of the switching device, and is configured to accelerate a turn on and a turn offan on/off process of the switching device, wherein charging of the switching device is accelerated when the second signal route is closed and the switching device is turned off and discharging of the switching device is accelerated when the second signal route is closed and the switching device is turned on.
