I can send and receive, but I have a new problem: If I add a delay of several hundred milliseconds before calling my send function, the sending will be normal, but if I don't add a delay function, gar...
This paper proposes a three-phase soft-switching PWM converter, which has the characteristics of simple circuit structure and fewer switching times than traditional converters. The switching of the ci...
I built a standard gate drive circuit using IR2117. Problem 1: VB and Vcc are generated using bootstrap technology, but no matter what the input is, there is always a 10V output, that is, the output d...
1. The power supply is 5V constant voltage, the maximum output current is 0.35A, and the resistance of the DC motor is 62.6 ohms. In the circuit below, if pin 1A inputs a low level, 1Y will output a h...
