DC power supply design and production of what materials
Okay, yes. N the contents of the full to give.
The simplest constant voltage DC power supply requires the following materials:
1, transformer
2, rectifier diodes or bridge heap
3, filter with electrolytic capacitors
4, the regulator circuit (78 series of fixed three-terminal or adjustable three-terminal regulator LM318, LM338)
5, other needs of electronic components (resistors, light-emitting diodes, potentiometers, etc.).
