I built a bandgap circuit at school according to the structure of a foreign chip, but the simulation found that the load capacity is not good; and I have to add capacitors to sacrifice bandwidth to co
The ATMegaZero ESP32-S2 is an ESP32 development board that looks just like the Raspberry Pi Zero, which means the shape and 40-pin GPIO interface are the same as the Pi Zero, and the same accessories
I would like to ask, how to choose the capacitance of the filter capacitor after the diode full-wave rectifier? The power supply voltage is 4000V, the current is 30A, and the frequency is 400Hz. I hav
