Background

In the power topology of power electronics, a medium-sized and large-sized multi-level topology circuit uses a plurality of groups of power switching devices, and the on and off control of the power switching devices needs a core controller to carry out wave-generating control uniformly. Because the system is bulky, the controller is often far away from the power module, and the control signal needs to be transmitted to the power module through the transmission line for control.

The control of the power electronic multi-level topology has strict requirements on time sequence and signal delay, and when a wrong wave-transmitting signal occurs in the wave-transmitting control system, unpredictable risks of the whole system can occur, such as a fryer, a large amount of damage to a power device and the like, which can cause potential safety hazards and great economic loss. When the medium-sized and large-sized multi-level topology circuits use transmission lines to transmit control signals, poor contact of terminals inevitably occurs, and at this time, the contact state of the terminals needs to be quickly detected and fed back to a main control system, and the main control system needs to process the fault at a required time to prevent the power module from working under wrong control signals. Problems arise with the electrical connections on the transmission path lines and false control signals can be generated.
