Hello.
I output six pwms through the microcontroller (STM32F103ZET6), and accordingly connect the complementary 2 to the input (J1) of the corresponding differential transceiver (CGD12HB00D) respectively, and then give it from the output (J2) of the differential transceiver to the gate driver board (CGD1700HB2M-UNA), which results in the power supply of the gate driver power supply indicators (DT3 and DT4) go out, as shown in Figure 1, but disconnecting any of the three gate driver input ports from the differential transceiver immediately restores the power indicators of the remaining two, as shown in Figure 2. What is the cause of this phenomenon and what is the solution. Very much looking forward to your reply.
