[0002] When using high-power power electronic commutation equipment, the pulse drive amplifier circuit is an important component. The gate signal directly output by the general integrated circuit is not enough to directly drive the high-power switching device. It requires an amplified pulse signal to reliably drive the switching device.

[0003] In application number: CN202022830378.8, a modular pulse isolation amplifier board is disclosed, including a power base plate and a plurality of power base plates detachably connected to the power base plate. The power base plate is integrated with a pulse transformer, a pulse input port, a pulse output port and a module power port electrically connected to the pulse transformer respectively, and the pulse input port and the pulse output port are respectively arranged on both sides of the pulse transformer. The power base plate is integrated with a base plate power port for supplying power to the power base plate, and the base plate power port is plugged with the module power port. The power base plate described in the utility model is detachably connected to the power base plate, and the disassembly and assembly are convenient and quick. When a power base plate fails, there is no need to replace the entire amplifier board, and only the faulty module needs to be removed, which does not affect the use of other modules and reduces the maintenance cost. However, there are still problems. The spring clip used to fix the pulse isolation amplifier board is bendable, and most of them are made of plastic structure, which is easy to cause breakage in the process of plugging and unplugging the pulse isolation amplifier board, and then the pulse isolation amplifier board cannot be fixed, so it needs to be improved.
