Maybe I thought things were too simple. I was tortured by the AT24C512 for almost two days. Without reading the data sheet carefully, I wrote the driver according to my (in)normal understanding. Singl...
I would like to ask, for example, if the system needs a +24V power supply, but it is not convenient to provide this voltage externally, then is it reasonable to use an amplifier circuit to amplify +12...
A parallel inverter consists of two thyristors (T1 and T2), a capacitor, a center-tapped transformer, and an inductor. The thyristors provide a current path, while the inductor L maintains a consta...[Details]
