functional description ：
The new energy traction converter is output to the middle part of the traction motor.Due to the existence of permanent magnet, even if the external power supply, permanent magnet motor rotation will produce reverse potential, inverter and three-phase isolation contactor between permanent magnet motor, to isolate the reverse potential of permanent magnet motor, avoid converter failure due to the permanent magnet synchronous traction motor on the power module, support capacitor and other components.
